Preschool fun, fantasy and education. It's time for Tubby Toast. Po and Tinky Winky are so excited that they fall over. They join Dipsy and Laa-Laa to watch two children dig a big mud hole. Some mud appears in Teletubbyland, and the Teletubbies play around in it. Laa-Laa has muddy feet and Dipsy has a muddy bottom. They find this very funny!
