Evil Pea has trapped Supertato and replaced him with an evil robot potato, programmed to do mean things and ruin his reputation. Will Carrot figure it out in time?

Supertato and the Tato Team face a trio of Evil Peas when Mummy Pea and Daddy Pea come to visit Evil Pea. They vow to help her take over the supermarket once and for all.

Evil Pea is annoyed by Supertato's winning smile, so she takes all the toothpaste in the supermarket! With no toothpaste, Supertato can't have a winning smile. The Tato Team soon realise that it is Evil Pea who has taken them all. Supertato keeps her distracted by pretending to share his brushing routine, while the others take back the toothpaste. When Evil Pea realises what's happening, there is a tug of war over the last tube, and she gets covered in it!
