Judy Reilly wakes up on her 16th birthday to find that her period has become a gigantic sentient monster that can say her name. This is perfectly normal and fine.

Cory responds to discovering her best friend is half alien the only way she knows how - by trying to dismember Judy for profit.

Judy's alien powers make her suspiciously good at volleyball, which begs the question - is there volleyball in space? This question will not be answered in this episode, or in this season, or at all, ever. We will never, ever know.
