Mecha Castle

The Mecha Castle is the first castle level in Yoshi's Story, and it is widely considered to be the hardest of the castle levels on the final chapter. It is home to many large sharp blue and red weapons that are referred to as swords. Gears are also abundant here, as well as spinning wheels much like the ones from Yoshi's Island. Some Compressors smash together, instantly defeating any Yoshi traversing the castle.

''The Yoshis finally got to the castle in the final page of the storybook. Behind all the noisy machines, Baby Bowser guarded the tree. Bowser was a tough baby, but bad guys finish last. The Yoshis won!''

Trivia

 * While the Message Block states that red swords will chase the Yoshi, they only move back and forth and do not actually chase it.
