There is this dungeon Red Petal Bastion when the first boss has these crazy abilities.

One of them abilities is when the boss polymorphed my character into a goat. 🐐

Also in order to not be some kid running around failing mechanics anymore is to eat the brightly sparkling cinnamon rolls. While dodging giant explosive neon green frogs.

Those boss mechanics are the Greatest Of All Time.

What other dungeons have silly, crazy, or awesome boss mechanics?
