As Justin is continuously getting annoyed by Alex breaking into his room and stealing things, he decides to create a female Frankenstein's monster to act as a 'body guard' and names her "Franken Girl". However, when Alex beats the monster and still manages to break into Justin's room, he tries to get revenge by casting a spell to make Franken Girl Alex's best friend but also casts a "spell lock" to stop Alex from reversing the spell. Although initially annoyed by Franken Girl's obsession with her, Alex soon takes a liking to her, which just makes Justin more mad and more eager to seek revenge. He soon thinks up a rather elaborate (and somewhat demented) revenge plan. This is the first episode of the series to be broadcast in High Definition.
