Wissper has a mouse in the house, and Mum does not like mice, so it's a quick transition to Hayley harvest mouse's lovely new nest. But Hayley isn't happy -another harvest mouse has built a nest next door blocking her view. Both mice stubbornly refuse to move so Wissper summons wise old Dan the panda to offer advice. He soon helps Wissper persuade the mice to take a different view.
