Tinky Winky, Dipsy, Laa-Laa and Po are outside in the cold when they spot the Tiddlytubbies, who are inside and warm. The Teletubbies put on hats, gloves and scarves to keep warm.

Tinky Winky finds a party invitation and shows it to Dipsy, Laa-Laa and Po. The invitation takes flight and the Teletubbies follow it to find a Tiddlytubbies' party.
