The Teletubbies do a Conga dance before the Magic Windmill spins and the Teletubbies watch some children painting with their hands and feet. Later, Tinky Winky comes down the slide inside the Home Hill. As he is about to walk forwards, he stops and says: "Uh Oh!" Somebody has spilled their Tubby Custard on the floor. Whoever it was has left footprints. Tinky Winky follows the footprints to the place where Dipsy is sitting with the rabbits. But Dipsy didn't spill the Tubby Custard. So Tinky Winky and Dipsy follow the footprints to the place where Laa Laa is dancing. But Laa Laa didn't spill the Tubby Custard either. Tinky Winky, Dipsy and Laa Laa follow the trail round Teletubbyland to find out who spilled the Tubby Custard. They soon reach the Home Hill and follow the footprints indoors to the place where Po is fast asleep. They all discover it was Po who spilled the Tubby Custard and they have a good laugh. The Magic Windmill spins and the Teletubbies watch a Tap Dancing Teddy bear in a carousel performing a dance twice before the Magic Windmill stops spinning and it is time for Tubby Bye Bye.
