Po gets on the Custard Train and makes lots of tubby custard - far too much for Po to eat alone! Po choo-choos off to find Tinky Winky, Dipsy and Laa-Laa so all the Teletubbies can share in the tubby custard. In Tummy Tales, the children take a ride on a steam train.

It's a cold day in Teletubbyland - so cold that it's snowing! The Teletubbies find big snowballs, dance with a snowman and watch children make a caterpillar out of snow.
