Lau Lau thinks that a squeak she hears is a mouse and tells the other Piplings. They are all excited about a visit from their new mice friends. They help her prepare a special welcoming party. When the cheebies arrive, they too help with the preparations, but no mice appear. It seems that they are too shy to come out and play. The cheebies pretend to be mice to make them feel at home! It's not until after that Yogo realises that the squeak is just a squeaky step and not mice guests at all. But never mind, they have all enjoyed their very special mouse party.
