Numbers - 10

Laa-Laa is out for a walk before the Windmill starts spinning. The Teletubbies watch some children learn about the number 10. Inside the House, Tinky Winky, Dipsy, and Laa-Laa sit on their seats. Po arrives on her scooter. She bumps into the slide and the walls until she falls off. Po sits down on the slide and the other Teletubbies stand up and sit down too. They all do it again and again and laugh at the noises they make. Eventually, they start laughing so hard and loud that they fall over. When they finally stop laughing, the Teletubbies watch The Magic Tree before the Magic Windmill stops spinning for Tubby Bye-Bye.

When the Teletubbies go to see The Magic Tree in the Portuguese version, they giggle as the harp tune plays and they run off, and they are also heard giggling whenever the tree starts to grow and the camera shows them one last time before the event starts, just like in the Russian dub.
In the Portuguese version, after the Teletubbies sit and stand for the last time, when the camera cuts to Po laughing as she sits on the slide, Tinky Winky, Dipsy, and Laa-Laa are not heard laughing until Po falls over. Additionally, they are heard giggling one at a time when the camera cuts to Noo-Noo looking on at the Teletubbies.
