In Teletubbyland, Dipsy listens to a Voice Trumpet say the nursery rhyme 'Doctor Foster'. Then the Teletubbies watch some children playing with water. A cloud appears in Teletubbyland. The cloud rains and makes a puddle. Laa Laa steps into the puddle, Dipsy steps around the puddle, Tinky Winky steps over the puddle and Po rides her Scooter through the puddle spraying the other Teletubbies. The Teletubbies love Po very much.
