Pingu is at home, playing aeroplanes, when an envelope is delivered. It’s for Pingu, and when he opens it he sees that it’s a card inviting him to a birthday party. Pinga wants to see it, but Pingu won’t let her, and Mother eventually has to intervene. Mother looks at the card and gives Pingu a fish to pay for a present. Pingu is just on his way out of the door to get the present when Mother tells him to take Pinga with him. Pingu and Pinga is not too happy about that, but Mother insists. At the toyshop, Pingu eventually decides to get a model aeroplane as the present. On the way home Pingu continues to not be very nice to Pinga, this time by hiding from her and being rude to her. While backing away he trips and drops the present, which slides into a small crevice that then gets partially blocked by a small fall of ice, with just a bit of the ribbon from the present sticking out. After searching for a while, Pingu spots where the present has gone and tries to get it out by pulling on the ribbon, but it won’t budge. Pinga says that she’s small enough to go through the gap to get the present, and Pingu is delighted when she gets it. When they get home, Pingu explains to Mother what has happened and sets off for the party, taking Pinga with him to her delight. When they arrive Pingu explains why he’s brought Pinga along as well, and Pinga gives the present.
