Burt the Bashful

Burt the Bashful is the first boss in the very popular game Super Mario Wrold 2: Yoshi's Island for the SNES. He becomes super sized by the enemy Kamek, and will then start jumping around the room trying to kill you. Once you throw six eggs at it, the boss will turn red, and then die. Each time you hit the enemy, he will become smaller and smaller.
