Brain Freeze

Summary
A new ice cream shop has just opened up across the block. With whimsical flavor names, futuristic furniture, and a cute mascot named Puk Puk, Yumbobo is threatening to put Brain's shop out of business. It's gonna be a rocky road.

Plot
Arthur, Muffy, Buster, and Francine look at a poster for an ice cream store called Yumbobo. Brain criticizes their overly-fancy marketing. As Binky enters to tell them about Yumbobo's penguin mascot, everyone except Brain runs outside.

Brain Freeze

Brain visits Yumbobo, and despite enthusiastic staff and unique flavor names, he is still not impressed. At his house, he examines that all of Yumbobo's flavors are the same as the ones in his store. He shows Buster, who suggests that Brain add gimmicks to prevent his store from going out of business.

Brain offers a free "chemical analysis" with customers' ice cream, which Francine and Muffy do not find interesting. Muffy suggests that he sell an "experience" instead of ice cream, and makes a fake story about the ice cream shop's history; Brain refuses to lie and leaves.

Worried that the ice cream shop could go out of business, Brain daydreams his mother being employed at Yumbobo. He goes to Jack's Joke Shop and buys a polar bear mascot costume. He stands outside the ice cream shop, but gets his free samples taken by Binky and a bee gets into his costume.

Serving himself at the ice cream shop, Buster attempts to juggle ice cream, but ends up mixing the flavors together. He tastes it and enjoys it, and Brain gets the idea to create an ice cream mixing lab at his shop. Two Yumbobo employees visit the store, to which Brain says, "I knew you'd be here sooner or later!"
