When Toast is kidnapped at the party, Unikitty becomes a detective to track him down. On the way her and the gang run into secret passageways and clues.

Hawkodile is tired of having to take care of the gang so much on their vacations, but they eventually persuade him as long as they follow his vacation training. They're put through selfie training, eating metal to gain guts of steel and to hold it in for the bathroom in order to be prepared for the next vacation.

Puppycorn is annoyed that Unikitty is always helping him and treating him like a little kid. Not wanting to be a "little brother" anymore, he eats some of Dr. Fox's "growing taffy" to literally grow bigger.
