S1·E42 Mark and Zoe Cooking

Po is sad and lonely because she has no one to play "Pat A Cake" with until Laa-Laa slides down coming to cheer her up. Po shows her how to play "Pat A Cake" and they listen to "Pat A Cake" and Laa Laa and Po happily play "Pat A Cake" together. Then Tinky Winky and Dipsy come in and decide to join in but they are interrupted by the Windmill. The Teletubbies watch Mark and Zoe decorate a cake with butter icing, chocolate, and strawberries. Back in Teletubbyland, the narrator sings a song about Dipsy's hat whilst the hat plays tricks on Dipsy.
