Crappy is Mutt's younger brother, and his squeaky puppy voice will melt the ears right off your head due to extremely high cuteness levels, especially when he sings a song. With his purple cape and red baseball cap, he masquerades as “Super Crappy!,” and often saves the day by saying just the right thing at just the right time. Like his sister Puddin', he's a little naive, but that's never stopped him before.

Crappy is voiced by Simba.
