Super Mario 3D World: Flower-12 -- Boss Blitz

It's time to take on the bosses in the Sprixie Kingdom. You'll start out in an area with 6 warp boxes, one of which is locked. You'll have to go through each warp box, defeat the boss, and you'll return here, with a Key Coin in place of the warp box you just went through. From left to right, the bosses are King Ka-Thunk, Pom Pom, two Hisstocrats at the same time, Boss Brolder, and Boom Boom. You'll want to deal with King Ka-Thunk, Pom Pom, and Boom Boom first, in whatever order you desire. Theses are quick boss fights and you won't need power-ups. Time management is key here. Once the battle is over, quickly warp out of there and ignore the coins. After those three, tackle Boss Brolder. This fight may take a little longer. After you beat Boss Brolder, the first Green Star will appear.

At the end, you'll fight two Hisstocrats at once. You'll want to get a Cat Suit and have one in reserve. If you're playing alone, pick either Peach or Luigi. When you stomp on one of the Hisstocrats, their extended jumps may allow you to hit the other one without touching the ground. This will be one of the longer fights, so try to take them out quickly and efficiently. The second Green Star will appear after you win. You'll want at least 100 seconds left after you beat them.

Once you unlock the warp box, it takes you to the last boss fight, Motley Bossblob. If you're still powered up and have at least 100 seconds left at the start of this fight, you should be okay. Grab the Double Cherries after he pounds the ground and chase after him. Once you defeat him, the third Green Star and a pipe appear, leading to a clock and the flagpole.

There are no stamps in World Flower.

Super Mario 3D World: Bowser-B -- Hisstocrat Returns

To the right of the stairs in an invisible block with a Super Bell. Take the gondola to the arena. Hisstocrat is a different color and the fireballs that rain down remain in pools for a while. Climb up the snakes and stomp Hisstocrat's head three times to make coins and the Green Star appear. The pipe leads to the flag. You need to complete Bowser-A to continue.

Super Mario 3D World: 3-B -- A Banquet with Hisstocrat

The pipe the Sprixie Princess created doesn't lead to World 4. It leads to a small patch of land. A circus tent with Bowser's seal drops down and the pipe to World 4 is blocked off. There are circus lights all over. Go to right of the gondola for an item block with a Super Bell. The gondola takes you down to the arena, then disappears.

Walk towards the center and Hisstocrat appears. He's a snake wearing a cape and crown. Rocks will rain down from the sky. Dodge them, then more snakes will come out of the ground. They have plates on their heads to stand on, some of which have Super Bells. Climb up the snakes to reach Hisstocrat and land on his head for a hit. He'll go back in the ground and it will start raining rocks again. After two hits, some snakes will not have plates on their heads and will hurt you if you try to stand on them. Others will have cracked plates which will break when you jump off them. The snakes will hurt you after the plate shatters. Defeat Hisstocrat with the third hit and the Green Star will appear. The pipe will take you to the flagpole.

After you beat the level, the tent will tilt to one side and the pipe will no longer be blocked. Head to World 4.
