The days before the Bridgeton Middle School dance, Nick Birch accidentally sees his best friend Andrew Glouberman's penis and attempts to avoid telling Andrew about it. Jealous of Andrew's penis, Nick fights with Andrew and believes he is taking an older girl to the dance, until she turns him down and embarrasses him at the dance. Andrew's Hormone Monster won't leave him alone, and convinces him to masturbate at inappropriate times. Jessi tells Nick that she likes him, and the two have their first kiss together. Nick and Andrew reconcile at the end of the dance. Later, at a new sleepover, Nick sees Andrew's Hormone Monster (who insists he is not a "pubertyfairy") leaving his room, whom Andrew had originally assumed to be his imaginary friend.
