Justin's birthday has arrived, but as excited as he is, his friends seem to have forgotten (when in actuality, they are preparing him a surprise party). Divatox takes advantage of the misunderstanding to leave Justin a gift, a special bicycle equipped with a detonator. Unaware of this, he gets on, and discovers too late the bike has a mind of its own, not allowing him to get off until it reaches 25 miles, where it'll explode! (thetvdb.com)
