A living potato who is very famous in Peppa's world. He is often with Mademoiselle Potato on television, and is associated with Mrs Carrot, Sweet Cranberry, and Little Sprout. It can be implied that Mr. Potato is simply just someone in a costume but there will be no evidence to support this as the series is told from a child's perspective.
Mr. Potato is an active and popular figure. He is known by everyone, and is admired by them - but he remains humble. He enjoys spending time with children, and hosts many events, including grand openings and sporting competitions (such as puddle jumps).
Mr. Potato is a giant, golden-brown potato with dull red lips and a curled black mustache. His eyes are black dots. On his head is a pale brown hat.
