Lots of slapstick humor throughout.
Mild scenes of destruction in some episodes.
Plenty of nosebleeds, but they are all played for laughs.
One character consistently bashes, his head against walls/trees/whatever is nearby until he bleeds to punish himself. Played for laughs.
A girl eats her fish friend and picks off pieces of him to offer to others. The fish is seen crying and screams in pain. Played for laughs.
