Candace's gelatin party inspires Phineas and Ferb to create the biggest gelatin mold ever in a swimming pool. Doofenshmirtz invites Perry the Platypus over for tea in order to convert him to an ally: one way or another.

Episode Summary
Candace is hosting a gelatin party. Phineas and Ferb reappear using their molecular transporter and see the gelatin she's holding. Jenny offers them a piece of gelatin, and Phineas says that he prefers grape. When Phineas and Ferb eat the gelatin, Candace realizes that they won't do anything wrong, however Phineas and Ferb start bouncing on the gelatin. Candace tells them to get out of the house and make their own gelatin, where Phineas states that he knows what they're going to do today. Phineas and Ferb run out to Isabella's backyard to start using it as a gelatin mold. Baljeet adds his own spicy flavor to the recipe, and when the gelatin is done, Phineas, Ferb, the Fireside girls, and Baljeet all jump on the gelatin.

Meanwhile, Perry enters through a flower vase, but he ends up in a pink, girly headquarters which turns out to be Pinky's. Perry gets out of the lair and enters through the street, where Major Monogram says that Doofenshmirtz is inviting Perry to have some tea with him because he wants Perry to become his ally.

Inside Phineas and Ferb's house, it shows Stacy, Jenny, and Candace comparing the molds their gelatins take up. Candace's own is shaped like Jeremy's head, while Stacy's is shaped like shoes, with Jenny's as a dove. Stacy and Jenny look out the window and say that they think what Phineas and Ferb are doing is fun. They run outside to play with it. However, in Doofenshmirtz Evil Incorporated, Doofenshmirtz is using a Turn-everything-evil-inator on Perry because Perry refused to become his ally. Doofenshmirtz shoots everywhere and it blasts out his window, pointing straight to the gelatin mold in Isabella's pool. This turns the gelatin alive and evil, which everyone looks at Baljeet for adding the "evil flavor".

Baljeet gets scared and says, "Okay, I'm going home now." which leaves Phineas, Ferb, Jenny, Stacy, and the Fireside girls to defeat the gelatin without Baljeet's help. The gelatin swallows Candace when she tries to interfere, and Phineas, Ferb, and their friends use water to defeat it and set Candace free. Dr. Doofenshmirtz realizes that he won't hit Perry, and presses a button making anything that was hit by the evil ray come to his side to assist him. While a soap and a bar of toothpaste appear, the gelatin monster shows up and captures Perry. Thinking fast, he throws his hat, setting off the water sprinklers in the room and melting the gelatin. He then escapes, while Doofenshmirtz slips on the soap and the toothpaste falls into his mouth. At the end of the episode, Jeremy comes over with Linda Flynn and shows Candace a gelatin mold he made for her that spells out her name. Candace says that she's still sick of gelatin.
