Plot
When a weird, slimy monster at a Center prison facility escapes captivity, Martin, Diana and Java are sent to investigate. When they get to the prison, however, they find absolutely no trace of the creature – so M.O.M. sends them home, telling them she will keep them posted. Back at school, strange things start happening – all involving Martin. Eventually, Diana and Java realize that the weird creature from the prison crawled inside his body in an attempt to make Martin its permanent host. The situation is having a disturbing Dr. Jekyll and Mr. Hyde effect on Martin. If Diana and Java can’t stop the creature – Martin as they know him will cease to exist! In a b-story, Martin finally convinces Jenni to give him a chance and go on one date with him.
