Common Sense Note
Parents need to know that this animated series is pretty edgy for non-Adult Swim Cartoon Network fare. It includes a fair amount of fantasy violence (kicking, punching, throwing, etc.) and some crude humor that isn't age-appropriate for younger tweens. There's also some salty language ("pissed," "screwed," "crap"), and characters are seen drinking beer, sometimes to the point where they act drunk and/or get sick. Occasional secondary characters are based on racial/ethnic stereotypes.
Mordecai has a crush on a cardinal.
Lots of fantasy violence (kicking, throwing, punching, shoving, etc.), but no one really gets injured.
Words like "pissed," "screwed," and "crap" are audible.
The show isn't out to convey any specific constructive messages/take-aways. But you could argue that it promotes creativity with its interesting storylines and characters.

Beer drinking is visible; occasionally someone gets drunk and/or sick as a result.
