Pingu comes out of the igloo to play, sees a hose lying on the ground and then hears voices coming out of the end of it. He follows the hose to its other end and finds Father and Grandfather in the shed doing some bottling. They are talking, and it’s their voices that Pingu heard coming through the hose. He shows them what is happening, and they’re surprised. He then takes the hose, and plays a trick on Pinga by making her believe that the snowman is speaking to her, and a similar trick on Robby by making him believe that a fish is speaking to him. Then he puts the end of the hose into the shed and attempts to fool Father and Grandfather as well. Their initial surprise soon turns to suspicion, and they find the hose and track it back to the source. Pingu is oblivious to this, and continues making noises into the hose. Father and Grandfather have an idea and place the end of another hose just behind Pingu and they, together with Pinga and Robby, shout into it, startling Pingu. After Pingu has calmed down they all have a good laugh.
