Mister That is a tiny person who lives behind a wardrobe in little Sophie’s bedroom. He loves everything milky and very often ventures in secret into the house to find food and treats. Nobody knows that he lives there until one day when Sophie rescues a cat and brings it to the house. One day the cat catches him and Sophie investigates only to find him in the cat’s paws. Being good hearted she gives him food, and decides that he cannot live behind the wardrobe, so she asks Mister That, if he would like to live in her beautiful doll’s house. Cheeky Mister That likes the idea, but only on one condition- that he gets a lifetime supply of milk. After some time the kitty and Misterr That get along so well that they drink their milk together.
