In Poison Ivy's lab, thunder and lightning go off outside and go past many different potions and chemicals, with Ivy excitedly remarking "Yes...", as a shadow of a living plant appears on the wall, which turns out to be Ivy holding up her new pet plant, which playfully licks her like a dog and barks.
Later, Ivy's walking down the corridor with her new plant pet which she's called Frankie, complementing him and telling him how good he is. However when Ivy bumps into Starfire, who wasn't looking where she was going, due to her reading a book. However, Frankie, thinking Starfire purposefully harmed Ivy, attacks her, even after she said sorry. Ivy manages to pull Frankie off of Starfire and explains how protective Frankie can be.
While out at the Capes & Cowls Café with Wonder Woman, Ivy pets her plant, who has abnormally become larger. The two are served milk by Steve Trevor, but Ivy stops him by saying that she asked for skimmed milk instead of whole milk. This makes Frankie angry and he attacks Steve by latching onto his face as he tries to apologize. Wonder Woman quickly starts to wrangle Ivy's plant off of Steve, telling Ivy that she needs to control Frankie.
Frankie, now grown into a ginormous size, starts to attack the people of Metropolis. Harley Quinn then arrives with her large mallet, along with Katana, Lady Shiva, Star Sapphire and Batgirl, who plan to stop Frankie, using an industrial strength weed-killer and blades and sheers. Beast Boy also turns up as an aphid, explaining how the plant will slowly but surely kill the plant. Wonder Woman then arrives to lead the attack on the plant. To try and protect her plant, Ivy then turns up to plead for mercy for the plant, explaining that he's not evil and that's just the way he grew.
After glancing at Katana's signature sword, Ivy gets an idea and whispered it into Katana's ear. Katana then sets to work, using her blade to slice away all the large roots and leaves, to cut the plant down to size. Ivy then picks her plant up, asking whether it's still Frankie, the plant quickly responds by barking and licking Ivy's face, and the two rejoice happily.
