Mother has hung out some washing, with help from Pingu. Mother has just gone back inside the igloo when the wind suddenly gets up, so Pingu decides to have some fun on an ice-surfer. He builds this himself, making the platform and mast from some stuff he finds in the shed, and for a sail using one of Mother's clean sheets that she has just hung out to dry. After some fun zooming around, while going up a hill the wind suddenly stops and Pingu and his ice-surfer go crashing back down. The sheet he’s used for the sail is now filthy. Pingu mournfully goes back home, is told off by his mother for dirtying the sheet, and has to clean it. As he is doing this, with not very much success, Robby comes along. By swish-swashing his tail, Robby very quickly gets the sheet spotless. Mother is very pleased by the result, and Pingu and Robby share a fish given to them by Mother as a reward.
