Maris Piper lives in a house with her fruit and vegetable friends. Today is Potato's birthday and they are going to have a party. The problem is that Potato needs a bath because he is covered in mud (Potato loves mud), but he doesn’t want to have a bath. She gets all the fruit and veg ready, makes the party hats, prepares pass the parcel and tidies the house. Every time she asks Potato to have a bath he disappears. Eventually Maris persuades him that baths are fun, so he has his bath and is very clean, ready for the party. However he disappears again… only to turn up inside pass the parcel!. OH POTATO!
