Hammy dreams that he finds a long, silver spaceship that takes him and GP into outer space. When he wakes up, however, the story seems to start all over again.
Hammy starts a book of records for a restless GP to break. GP decides to break the diving record held by Turtle, with a twist - he'll be diving through the sky.
GP builds a robot called 'BOROS' (Battery Operated Rodent of Steel) to do all his work for him so he can have more "thinking time," but BOROS ends up being a little too successful.
It's Christmas on the Riverbank and Hammy, Martha, GP and Turtle set out to find a tree and exchange gifts. But when a mysterious stranger steals their tree, the animals track it to a lonely cave deep in the woods and find a Christmas surprise.
