Parents need to know that in order to market this movie to older kids by getting a PG rating, the producers have included brief mild language and cartoon-style violence. Very young children may be scared by the machine that turns people into vegetables (literally).

Families can talk about Karen's "ends justify the means" justification for stealing a truck and other dishonest acts, and Rocky's reply, "But we're supposed to be the heroes." Older kids will enjoy the way that the characters are aware that they are in a movie -- what people call "breaking down the fourth wall." Characters talk back to the narrator. When Karen is asked to explain her behavior, she says, "I didn't write this movie!"
