Overview: 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.
