The Teletubbies love playing Boo! Some children learn about the number six. Afterwards, Tinky Winky, Dipsy and Laa-Laa get their knees dirty and have fun getting them clean until Po comes in all dirty. Tinky Winky, Dipsy and Laa-Laa try to wash her, but she doesn't want to and runs around until Po gets her tubby sponge to wash herself when the others wash her. She is all clean and everyone is all clean too until the Magic Windmill stops spinning (offscreen) and it is time for Tubby Bye Bye. Featuring: The Children of Duncombe School, London
