Horrifying creatures crawl around in the Tubbytronic Superdome nursery, feeding on Tubbytoast and Tubbycustard.

The Tiddlytubbies were first introduced in the episode Babies. They are baby Teletubbies and live in the Tubbytronic Superdome with the Teletubbies and Noo-Noo. All of The Tiddlytubbies are voiced by Teresa Gallagher. There are 8 Tiddlytubbies.—NatZee
