Crusher

Crusher is a very different monster than the rest of his friends. When he sits down, he is even taller than the tallest monster. Despite his name, he is a really nice monster. In the episode Sad, To An Extreme Level, Mochi is depressed, and when Crusher gives him a hug, he feels better. Crusher is also the first monster to realize that Owl City is right beside Monster World. In the episode: A New Threat, he turns evil by a unicorn named Wishful for most of the episode. But he turns good again.
