Corn is sick and tired of Evil Pea's plans failing because she's always boasting about them. When Evil Pea accidentally gets stuck in a block of ice, Corn takes the opportunity to take over and become Evil Corn. After confronting Supertato, Corn plans to cover the supermarket in butter. Evil Pea and Supertato work together to stop her, and Evil Pea knows what Corn's weakness will be – boasting! At the top of Cereal Mountain, Supertato gets Corn to boast about her evil plan, while Evil Pea butters Corn to the side of the mountain.

After Supertato accidentally knocks the ice off Evil Pea's freezer, she seizes the opportunity to stay at Tato Tower. Supertato is excited to have Evil Pea over, but once inside, she uses her Freezy Hose to freeze Supertato out of his home. Luckily, Carrot has a plan. He goes to Evil Pea's freezer and turns it into Supertato's freezer. Evil Pea is furious and leaves Tato Tower to tell him to get out, leaving it unguarded. It's a race to reach the freezer first.
