When a group of polar bears wash up on the beach, Lily invites them home! One day Lily was playing on the beach with her Grandpa when she spotted something in the distance . POLAR BEARS! Lots of polar bears! All floating on pieces of melting ice. One evening, Lily is playing on the beach. And who should float in, but LOTS of polar bears! Lily is excited to welcome them home for dinner (of fish fingers and ice cream, of course) and to have them stay for a sleepover. Lily has even more fun with the bears when they go swimming, ice skating, and visit the fun fair - and it soon turns out that polar bears are really quite good at a lot things, becoming polar bear postmen, opening ice cream parlours, and even becoming astronauts!.
