Burt's Bouncy Battle

Burt's Bouncy Battle is the boss level of Chilly-Hot Isles in Yoshi's Crafted World. In this level, Yoshi must battle and defeat Burt the Ball to recover the yellow Dream Gem. Twenty Smiley Flowers are required to unlock this level.

Battle
At the start of the level, Yoshi is seen running ahead before being stopped by Kamek and Baby Bowser, who is balancing on a large beach ball in the water. Baby Bowser rolls over to Yoshi, telling him that the Dream Gems are his and that he won't be getting in his way this time. He then asks Yoshi if he thinks he can do it better than him, and Yoshi is given the choice of answering "Eh... Not so much" or "Sure I do!"

If Yoshi goes with the first response, Baby Bowser becomes excited and boasts that Yoshi knows awesomeness when he sees it, then falls off the ball and into the freezing water. Baby Bowser becomes angry and Kamek claims it was Yoshi's fault for not being honest. If Yoshi replies "Sure I do!", Baby Bowser becomes angry with him and falls into the water, which makes him even angrier. Kamek then uses his magic to transform the beach ball and a giant pair of striped pants into Burt the Ball.

At the start of the battle, four hearts parachute toward Yoshi. Burt begins attacking by hopping three times from one side of the platform to the other. Next, he uses a whistle to call in Bumpties, which fall out of the air, bounce off Burt, and slide toward Yoshi. Yoshi must eat one, spit it back out at Burt to make him lose his balance, then do it again before he regains it. If Yoshi is quick enough, Burt falls into the water upside down. Yoshi must then Ground Pound the revealed bandage to damage him. Burt then flies into the background and summons five Beach Burts in rubber rings who throw beach balls at Yoshi when he blows his whistle.

After this, Burt jumps back onto the platform and rolls from one end to the other, jumping in the middle. He then summons more Bumpties, some of which are in buckets. Yoshi must repeat the damaging process. After he damages Burt a second time, he flies back into the background and summons more Beach Burts. The ones at the ends throw more beach balls, while the one in the middle spikes Burt toward the center of the stage. He then Ground Pounds one side of the platform and jumps to the other as more Bumpties in buckets slide down. After this, more Bumpties fall toward Yoshi. If he is able to damage Burt one more time, his pants fall off into the water. Burt is so embarrassed that he deflates and flies away. After he is defeated, it is revealed that the yellow Dream Gem was in his pants all along, and Yoshi collects it.
