S2·E120 Christmas in the UK

Dipsy remembers the snow. The Teletubbies watch some children gospel singing and go into the snow. They are walking very carefully because the snow can be very slippery. When Tinky Winky slips, he begins to slide. It looks like fun so the other Teletubbies slide in the snow too. Laa-Laa wants to slide too so she slips and slides down the snow. It is Po's turn so she slides down the snow too. Tinky Winky, Laa-Laa and Po want Dipsy to play sliding, but he is too scared until he slides down the snow. He is not scared anymore when the other Teletubbies and narrator say "What clever sliding".
