Goomboss Battle - The Switch Star

This is a mission unique to the Nintendo DS.
There are other missions to complete inside the Mario painting. If we go in as Mario, we can complete one of these missions. We slide down the trunk and head to the right. We land in the haze and take damage. We walk up the narrow slope and take out the Piranha Plant. We jump across three of the four gray tilting platforms and land near where we came in. We take out the Goombas to clear the runway. At the end is a tall metal cage with a Heart. We need to reach the top of the cage, so we need to do wall-jumps (wall kicks). A sign near the cage explains "Hop onto high places with the wall kick. Just jump at a wall, then jump again when you hit the wall. Keep in mind that only the superhero with the red cap can pull this move off." Near the Star Switch is another sign: "In front of you is a Star Switch. Step on it to make a Star appear in the course. Hurry to collect the Star before it disappears! Don't forget that you can check the Star's location on the Touch Screen map."
We step on the Star Switch and the Star appears at the top of the ledge inside the metal cage. We run to the cage and wall jump up until we land on the grassy ledge. We run to the Star Sphere and break it for the Star. We get a message: "Wow! Another Power Star! You're getting stronger from the power of the castle. Do you want to save? You bet / Not now
Star Get #35, 6 Coins, 7 Lives
Since we are not warped out, we decide to see how Goomboss is doing. After falling in the haze and being hit by a Goomba, we fall into the trunk to see Goomboss. He says "You're Mario!!! What are you doing here?! My underlings locked you up in that room. Never mind. I'll deal with you myself! Now I will trample you as you have trampled us!"
The Goombas appear in front of him this time, so we can punch them into Goomboss. We get trampled by Goomboss, taking four bars of damage. We fell into the haze trying to get aroung them, but punched two Goombas into him. We run into Goomboss, but get in a hit from behind. We take more damage, but get in the last hit we need. Goomboss says "Aaaaauuuuuuurrghhh! I am so angry I am cooking in my own succulent juices! The Goombas have lost... Again?! Is this our destiny?! To be trampled by oppressive feet for all eternity? No, we will definitely triumph next time! Yes, next time! The Goombas' fate is not defeat, but perseverance!"
He explodes into the key once again. We get the key and warp out. We can't do anything special with the key because we already unlocked the door.
The next Star is the Secret of Battle Fort.

Goomboss Battle - The Key to Mario

This mission is exclusive to the Nintendo DS.
After checking out Sunshine Isles, we decide to see what's on the other side of the door marked with an 8. We see a pink couch, a window to a balcony, and a picture of Mario! It jiggles, so we can go in it. Mario is still trapped somewhere, so we should be able to find him in here somewhere! We go in. The music from Hazy Maze Cave plays, which is a remix of the Underground theme. The world is set in a leafless forest. We slide down a tree trunk onto checkered tile. There is a purple haze below us. It's purple, so it's poisonous. We will take damage if we fall into it. Ahead are Goombas and three tree trunks bobbing in and out of the haze. We pass a Piranha Plant and climb onto a vine pole while dodging Lakitu. We climbed to the top of the pole and got a 1-up. There is a bridge leading us to the top of one of the tallest tree trunks in this world. We cross it, taking out the Goombas as we go. We kill a Piranha Plant and come to the center of the trunk, which has a hole in it. We can't see what's down it, but here goes!
We land on another tree trunk in front of a huge Goomba wearing a crown and red and white striped pants. He says "Bwa ha ha! I'm no ordinary Goomba... I am Goomboss, the great Goomba, the grand poo-bah Goomba. That Mario always stomps on us. But now the tables have turned! I locked him up in a room. I bet he's crying like a baby. I have no business with you, so scram! There's no way a prehistoric wimp like you could beat my stupendous stomps!" Well, we now know what happened to Mario. That must be the voice we heard calling for help! Fiend! We shall now do battle!
The battle music starts. Three Goombas appear behind Goomboss as he marches around in a circle around the center of the tree, which has the purple haze. We do not want to fall in there. We run ahead of him to reach the Goombas behind him. We take a hit from a Goomba and spit another at him. He turns around, grows bigger, turns redder, and his eyes get more crazy rings. More Goombas appear behind him and he moves faster. We eat another Goomba and hit him with an egg. He grows bigger, redder, has more crazy rings around his eyes and more Goombas appear behind him. He also moves even faster. We hit him with another egg. His eyes shake violently as he stands still. He says "Beaten by a pip-squeak like you... How did that happen? Is it just the Goombas' fate to lose? I have Mario locked up in a room, you know. This key will open the door to his room! I still can't believe you beat me." He swells once again and explodes into a bunch of Goombas that disappear and a key. The key is a gold key with white swirled into it. It wears Mario's cap and has the letter M on its handle. Yoshi takes the key and poses with it.
1 Coin, 5 Lives
We go to the red door and Yoshi unlocks the door and goes inside. We hear a drumroll, then a fanfare remix of the Mario theme as Mario flips out the door, takes off his cap and poses. We get a message: "You've rescued Mario! Now he can smash Bowser in style. Red caps are everywhere. Grab one to turn into Mario. Thwart Bowser's sinister plans with super moves!"
The next Star is ? Switch.
