A frigid wind blew through the dim and draft corridors of Castle Bleck. Bowser, Peach... and even brave Luigi were gone. Mario was the only hero left. It was up to Mario to stop the dark prophecy. Every world hung in the balance. What thrilling conclusion awaited our hero? Mario ran to the count's inner sanctum, his mustache fluttering in the breeze...
Tippi says it's just her and Mario now, which reminds her of the time they first met. She apologizes, saying she promised to help Mario find his friends, who are now gone forever. Mario disagrees. Tippi thinks he may be right that they survived. They are heroes and she's going to believe in them, and HIM most of all.
In Castle Bleck's Inner Sanctum, you'll find Coptas, Poison Pokeys, and Cursyas. You'll also find some Mushrooms in item blocks. Go through the door and you'll find Magiblots and no way out. Use Tippi's power to find a hidden door. In this room, you'll find rising platforms, along with Parabuzzies and Spiky Parabuzzies. You'll come to a dead end. Flip to find a path around the tall platforms, then go through the door.
There are infinite platforms in this room. In the middle of the room, when you reach solid ground, flip to find a pipe. Flip and use Dottie to shrink to pass through a tiny hole in the wall. This leads to a chest with a key. Return to the infinite platforms to unlock the door. The door leads to a room with many Mega Muths, with 200 HP and 8 attack. Some of them are in 3D.
Go through the door and you'll find a hallway that dead-ends. Flip and you'll see several doorways to your right and left. These lead to different hallways, some with items and most with enemies. From the door, go right four times to find a chest with a Shooting Star. From the door, go left once to find a door.
From the door, take the first right to find a chest with a Super Shroom Shake. To reach the next door, from the door, go left three times. In the next set of hallways, take the first right, then the second right, then walk backwards to take the first right to find a chest with an Ultra Shroom Shake. Go through the first right to reach a door. The door leads to some stairs with an Ultra Shroom in an item block and a Save Block. When you're ready, go through the door.
Tippi feels something powerful on the other side of the door and she thinks it may be the Chaos Heart. Count Bleck and Nastasia are here. "Bleh heh heh heh heh... I see you've come at last! So you really are the hero of the Light Prognosticus. But you are far too late to stop the Dark Prognosticus and me... Count Bleck! All worlds will soon end. Come to grips with that now, for you cannot stop it. I suggest you make yourself comfortable and enjoy this one, final spectacle!" Tippi asks why he wants to destroy everything and how could he do this. "Count Bleck does not care about any world! They are all meaningless. Better that I destroy them! Better yet, I shall make it as if they never existed at all!" Tippi asks Blumiere if their meeting was meaningless as well. "You know the answer, dear Timpani... Count Bleck does not have to tell you... But the hour has grown too late. You should know that by now." Tippi knows the only want to stop this is to defeat him, which is why she and Mario are here. "BLEH HEH HEH HEH! BLECK! Very well! But I will also do what I must! Count Bleck is the deleter of worlds! My fate is written in the Dark Prognosticus. Do not think for a moment that I will hesistate to strike you down. ALL NOW ENDS! Leave me, Nastasia! I will deal with these two ALONE." Nastasia tries to object, but he says, "Count Bleck demands it! I will not say it again." Nastasia leaves and he continues, "Are you prepared, hero? Our duel will be worthy of the last clash the world will ever see!"
Count Bleck has 150 HP and 8 attack. He shoots out blasts of dark energy. He's also invincible, guarded by a shield of the Chaos Heart. "How laughable! Is that all the heroism you can muster? Let me show you true power! You can't so much as tug on the cape of Count Bleck! You have failed! Bleck! I expected more potency from the hero of the prophecy! I will watch your game end, and then your precious worlds will end soon after!" He prepares a huge energy blast. Tippi wonders if this is the end. Someone asks if they're giving up already? It's Bowser, telling Mario to man up, as he never gives up this easily when he attacks his castle. "Bleh heh heh heh heh heh... So you ARE alive, then!" Peach and Luigi show up. Peach says they'll never let him destroy everything. Luigi says they won't let him get away with this and that they're not giving up. Count Bleck will never win. Tippi asks how they got here. Bowser fell through the floor before the ceiling could crush him. Peach landed on Bowser, which was a surprisingly soft landing. Luigi doesn't know what happened, but Peach found him unconscious. He's ready to defeat Count Bleck. Bowser says Count Bleck will have to deal with all of them.
"Bleh heh heh heh heh heh... 'When the four heroes are united...' It is all as foretold." Light flashes. "What... What's this?" The heroes start glowing. Peach asks what's happening to Count Bleck. Pure Hearts appear around him and shatter the Chaos Heart's barrier. "Bleh heh heh heh... huh?! My barrier... is gone?!" Tippi quotes Merlee, saying, "Four heroes unite, their hope burns forth light to shatter the walls of blight." "So be it... says Count Bleck! But don't celebrate just yet. Your precious worlds aren't safe until my last breath! Let us finally end this! Now the true battle beings... with Count Bleck!"
You can now damage Count Bleck and select from the four heroes. Count Bleck likes to move around and flip to change his location. Hop on the platforms to reach him. You'll want to stomp him, then get out of the area to avoid any attacks he has up his sleeve. He can summon a black hole that will slow you down and do a lot of damage if you get caught up in it. Run away from it until it goes away.
When you defeat him, he says, "BLEHHHH!" The Chaos Heart disappears, then reappears near the floor. Count Bleck appears near it, looking worn out. "Ex... Excellent..." Nastasia appears near the count. He says, "You have won... Now finish Count Bleck. Dispatch me and the Chaos Heart will disappear. The prophecy will be undone..." Tippi asks why it has to end like this. "Timpani... when you vanished, I searched long for you. I never gave up looking... I searched and searched... But I never found you. Without you, the world had no meaning or joy... So I used the forbidden prophecy of the Tribe of the Ancients to end all worlds. I wanted to destroy everything that had taken you away from me..." Tippi says that she's here now and none can keep them apart anymore. "It is too late. Count Bleck has done so much evil... It must end. Just knowing that you are still alive... And knowing that the world you still live in will continue... It gives me peace. I do not have long to live. You must end my game before The Void destroys all..." Tippi protests that they're together again.
Nastasia looks shocked and tells Count Bleck to look out. She's hit by a familiar-looking blast. "Na-Nastasia!" Someone calls her a silly assistant for absorbing the attack to protect the count. They call it an adorably hopeless gesture. It's Dimentio, saying he was about to give the count the everlasting peace he desperately wants. Tippi is shocked that Dimentio's alive. He says this is his moment. Even if the count dies, the Chaos Heart won't disappear if he continues to control it. He needed the Pure Hearts to beat Count Bleck, something he couldn't do on his own. Instead, he has the heroes do all the sweaty labor for him and they even used up the Pure Hearts to defeat the count. If they make greeting cards to thank people for helping with evil plans, he owes them one. Now, none of them hold any value, so he's ending their games. He tells Mr. L that they're all his. He snaps his fingers and Luigi starts flapping his arms against his control. A sprout appears on his head and he says, "I AM MR. L! Master Dimentio, what is your bidding?" Dimentio explains he sent Luigi here after planning a seed in his unconscious, which has now sprouted. He sends Luigi off to prepare for his big entrance. Dimentio takes the Chaos Heart, saying, "Get ready for the greatest magic show you'll ever see!" Both are absorbed into the darkness. Someone says "GREEEEEEN!" Something gigantic appears with Luigi's head and feet and Dimentio's torso. Dimentio explains that the Dark Prognosticus says Luigi's the ideal host for the Chaos Heart and he added his own power to the concoction. "No... Stop!" says Count Bleck. Dimentio makes Count Bleck, Tippi, and Nastasia disappear, saying he'll squeeze the life out of them later. He tells them to wait in the dimension he sent them to. He enters the robot, saying the Chaos Heart is his. He'll destroy all worlds, create perfect new ones, and become king of all worlds.
The platforms in the room start moving and making faces. This is Super Dimentio, with 200 HP and 6 attack, but he's invincible right now. He'll target the heroes and either land on them or shoot at them. Keep moving so he can't hit you. He can also punch you. The platforms also shoot at you, so be careful. After a while, Super Dimentio announces it's destruction time and he'll begin with the heroes as they wallow in helplessness like upside-down turtles. He calls out, "L-POWER!"
On Flopside Tower, Merlon says the worlds are trembling. He wonders if the end is nigh. Norlem calls this unfortunate. The worlds that the heroes have visited start warping. In Dimension D, where Dimentio sent Tippi, Count Bleck, and Nastasia, Tippi says they have to do something to save Mario and the others. "We cannot. Without the Pure Hearts, there is not way to counter the Chaos hHEart. All we can do is give up." Tippi is shocked that Count Bleck would give up after promising long ago that they would find happiness together. She asks if it was just a lie. "It was no lie. But without the Pure Hearts, all worlds are doomed. What can we do?" Tippi tells Blumiere to snap out of it, asking how he can think that after they've suffered apart from each other. They found each other because they stayed alive, so she can't believe he'd admit defeat. She's not giving up because he promised they'd find happiness. Someone says Tippi's right. Mimi and O'Chunks flip in. "My minions... How did you find us here?" Mimi says they followed his smile. O'Chunks says that Nastasia said they'd be here. "Nastasia..." O'Chunks says Nastasia sacrificed herself to save him. He also promised the count his life and will live up to that promise. Both he and Mimi want to help, declaring their loyalty. "My... My loyal minions..." Black hearts appears, then reveal themselves to be Pure Hearts. "Hmm... What's this? Pure... Hearts?! But why?" Tippi explains that they are the feeling of our souls. As long we feel love, they live on. Tippi says she'll take them to Mario.
Dimentio says they should stop wasting time and finish this. Lights flash and the Pure Hearts surround Super Dimentio. He thought the heroes wasted them fighting Count Bleck. Super Dimentio is no longer invincible and the heroes are fully healed. Tippi rejoins them, saying the Pure Hearts have given them power. Now that you can attack, attack the head. Once you defeat him, he asks how they did it. He wonders how he could lose with the power of the Chaos Heart and Luigi. He asks if the prophecy has been undone. Peach says the prophecy was wrong all along. Bowser says Dimentio believed in the prophecy and they believed in mopping the ground with him. Tippi says nothing is decided entirely by fate and that everyone can choose their destinies. She bids him farewell. They'll add a footnote about his failure to the prophecy. Dimentio says this isn't finished. They can't stop this or escape. He has one last surprise. Super Dimentio spits out the Chaos Heart and Luigi. Luigi wonders what he's doing there. The Chaos Heart disappears.
Count Bleck, Mimi, and O'Chunks appear. "So it seems the end of all worlds is really upon us..." Tippi asks if defeating Dimentio wasn't enough to stop it. "I thought the Chaos Heart would disappear if the person controlling it fell... Dimentio... must have left behind a shadow of his power to continue controlling it. It won't last long... but it may be enough to ensure the end of every world..." Bowser asks what they should do now. "There is only one thing left that we can do." Count Bleck summons a large, cracked door. "This way!"
The door leads to the alter where the wedding ceremony between Peach and Bowser was performed. Count Bleck asks, "Timpani... Do you still... Do you still love me?" Tippi says she does. "Then you must come with me." O'Chunks asks what they're doing and he explains, "We will use the Pure Hearts again, this time to banish the Chaos Heart. All we need is true love... And that is something I am lucky enough to possess... But... With the Chaos Heart gone, the Pure Hearts and those linked to them... They may cease to exist." Mimi doesn't want him to go away. "All of this is my fault. It is my price to pay. I do not have long to live anyway. But you, Timpani... It pains me to know this may cut your game short... Still... There is no other way to end this." Tippi understands. "Timpani..." She says nothing else matters as long as they are together. The ground shakes violently. Luigi announces that the end is happening. "We must go, Timpani..." Tippi agrees. They fly up to the alter, where the Chaos Heart is. "There were so many things I wanted to say to you.. but I could not find the words." Only one thing matters to Tippi: she never got to return his question. She asks if he loves her. "Of course... I have thought about you every moment since you disappeared... But I have caused you so much suffering..." Tippi says her life would have been more carefree if she hadn't met him. "But I had to be with you, Timpani. I will never apologize for that..." Tippi knows that and says she loves him. "And I love you, Timpani... Hundreds of thousands of years from now, that fact will not have changed..." Pure Hearts surround the Chaos Heart and engulf it. The world starts shaking. Bowser wonders if they're too late. Luigi hears something. They all hear bells chiming. The ground stops shaking. Peach says the bells are giving their blessing to Tippi and Bleck. In the worlds they've visited, The Void slowly disappears and the worlds are restored, including the Sammer Kingdom.
Blumiere: Timpani... do you remember the promise we made to each other that day?
Timpani: Yes, I remember...
Blumiere: If there was a place where we could be happy together, we would find it. Will you come with me to that place now?
Timpani: Blumiere... Of course... I will always be with you...
Back on Flipside Tower, Luigi wakes up Mario. Mimi, Nastasia, and O'Chunks are with the heroes. Nastasia wakes up, thrilling O'Chunks. Peach draws their attention to the sky, where The Void is closing. Someone says it's a sign that the Prophecy of Destruction has not come to be. Merlon appears, saying all worlds have been saved. He thanks them for a job well done. He looks around, wondering where Tippi is. Mario explains what happened. Merlon accepts that she is gone under the guidance of the Pure Hearts. Peach wonders what happened to Count Bleck and Tippi and Merlon thinks they were lost when the prophecy was nullified. Nastasia disagrees, saying they're alive, fulfilling their old vows after overcoming time. She starts crying that she's all alone. O'Chunks agrees they're alive but says she shouldn't shame the count by crying. Mimi says they're still together, so they can build the count's world. Nastasia agrees that the count wouldn't approve of her crying. She also wants to create the count's world of love and not war. She suggests they pencil in an appointment for hope. Merlon comments on how farewells are bittersweet, but unavoidable. To feel sadness is to live, but the future is a blank page. After that profound musing, Merlon announces that he is hungry. He asks Saffron to make some snacks. Bowser likes this plan and starts heading for the elevator with the minions. The bros and the Pixl leave as well. Peach starts to leave, but stops when Merlon mumbles something. He wonders if Lady Timpani is truly happy. Peach says she is. Merlon agrees and they leave to get some snacks.
So the dark prophecy was averted and peace reigned. The Dark Prognosticus again faded into history... Count Blumiere and his love, Lady Timpani, both vanished. Where did the pair go? None know. And so the story of the lost book of prophecies comes to an end... May we meet again in another time and place...
Roll credits! After the credits roll, you'll see Lady Timpani and Count Blumiere, standing in a field together near a tree.
