The Tubby Sponges are located at the Control Panel. The Teletubbies use them to clean them selves. Tinky-Winky's spongecase is purplish blue, Dipsy's is green, Laa-Laa's is yellow and Po's is reddish pink. The Tubby Sponges are locked in the sponge cases. To unlock them, one of the Teletubbies talks into a little microphone beside them asking for the Tubby Sponges, then they wait for a few seconds and the cases light up and make noises, and then the Tubby Sponges are ready to take out.
The Teletubbies also have a little song when washing themselves, "Wash Wash Wash, Wash Wash Wash, Tubby Tubby Tubby Tubby, Wash Wash Wash". Occasionally, a Voice Trumpet will either sing the song with them or tell them which body parts they need to wash.
