The Great King Bowser

"I want the biggest, baddest, most awesomest...ROBOT!"

- Baby Bowser

The Great King Bowser is the first boss of Shadowville in Yoshi's Crafted World, fought in the level of the same name. It is a large mecha piloted by Baby Bowser, with Baby Bowser's face as the cockpit and two arms with a certain weapon attached to them.

In phase 1, they are cars that can be driven across the platform Yoshi is on. In phase 2, they are squeaky hammers that are kept above Yoshi until the second to last second, after which it slams down. In phase 3, they are boxes holding pencils, which can be placed on the edges of the arena while the pencils protrude out of the boxes.

The robot's other attacks are to release missiles that travel across the stage horizontally or vertically, which include regular missiles and Shy Guys riding them, which can be eaten for eggs. In phase 2, it introduces an attack where it releases gears that bounce from one side of the arena to the other in synchronization.

The arms can be destroyed at any time by throwing a egg at them. Once both are destroyed, the robot malfunctions and the cockpit opens up, leaving Baby Bowser vulnerable. Baby Bowser can breathe fireballs that hover over Yoshi before falling down onto the arena, and the robot can still use its missile and gear moves. However, all it takes to stun Baby Bowser is to throw an egg at him, causing him to land on the platform Yoshi is on. After this, Yoshi can damage him by ground pounding him. Afterwards, Baby Bowser will jump back in the cockpit and all but the support of the robot will be raised to reveal a carousel of three Bullet Bill cars, which will be spun at the level of Yoshi's platform. In the second phase, this is changed to four cars, and the robot changes direction more frequently. Once this attack ceases, the next phase begins.

After Baby Bowser is ground pounded for the third time, the robot breaks apart, leaving just the platform it was stationed on.
