Humphrey's a handsome rough haired ginger guinea pig - with attitude. He's adventurous, accident prone, overweight due to an unquenchable appetite, and has an inquisitive nature that leads him into all sorts of trouble.

Humphrey shares his cage with his rather timid companion, a smaller smooth haired black guinea pig named Sooty. They are devoted, enjoying a surprisingly inclusive social life with the family.

In this adventure, Humphrey enjoys a night of freedom, but realises that being free is not as much fun as he was expecting!
