Floral Derangement is the second half of the 14th episode of Dave the Barbarian.
When Fang messes with Dave's life, Dave threatens to send her to Ms. Bluelung's School for Really Cute Little Girls, an educationally evil punishment which Princess Candy suggested. In order to avoid being sent to Ms. Bluelung's, Fang must promise to stop messing with Dave's life, but she breaks her promise. She swipes some of Oswidge's magic and makes some of Dave's flowers—his prized Purple Winkies—grow huge. Surprisingly, gigantic ravenous flowers cause a few minor problems, which Fang struggles to conceal from Dave.
