It's sort of 'Ren 'n Stimpy'ish. The animation is definitely cute, but there's blood and decapitation and a level where the approaching footsteps of the boss cause rampant diarrhea among varius animals.
I'm dead serious. I saw this owl in the background, and I was like, that owl looks significant, I'm going to go over there and hit the default action button to see if he does anything, and he shit all over me.
So, basically, Castle Crashers is awesome.
