DC Animated Universe

"Baby Boom" is the fifteenth episode of Gotham Girls and the fourth episode of Season Two.


Harley Quinn and Poison Ivy visit a wax museum, hoping to steal the (real) jewels off of a wax figure of Princess Adjani. Ivy gives a pile of pollen to Harley to incapacitate the guards with. Harley, curious, sniffs it as Ivy explains its effects: It carries a rejuvenating chemical that will cause whomever is subjected to it to regress to infancy, as Harley learns firsthand.

With Ivy briefly distracted by the guards she was about to incapacitate, the baby Harley crawls away. While Ivy worriedly looks for her, she finds the statue of Adjani again, swipes the jewels, then finds and destroys a wax statue of the Joker. Ivy writes it off to onlookers as "father issues," then drives away with Harley in an organic baby seat.

Interactive Segment[]

While Harley is crawling around, the viewer can press the buttons on pedestals as she pauses by them to see the statues, which are built in the likeness of Zatanna, Lobo, and Superman.

Background information[]


  • At the end of the episode, one of the security guards asks his partner, "What kind of whacko names their kid Harley Quinn?" and the other guard shrugs. This could be a reference to director Kevin Smith, who named his daughter after the Batman villainess.
