Drug references (SPOLIERS!)
I caught at least two, that time when Dougal was discussing sugar with Dylan, and the other other time was the most obvious of all when the town got unfreezed, and Dylan said that things about grass. Also, the ending when Dougal had decided to stay off sugar, that evil sadist girl waves a sugar cube in front of him? I mean, COME ON!
Dylan sure had several good quotes in this movie, but as a character in a kids movie, I found him quite inappropriate.
