Down the chimney with googol and googolplex

Googol and Googolplex are on a mission to learn about Earth.

The alien robot duo begin by collecting a number of items including a blackbirdís song, snowballs and a chocolate bar. Pippa and Troy are happy to help, especially when they get to ride to the North Pole in a spaceship. But when they return, Martin, the bully next door, sees something that he shouldn't.
