After a nasty incident with a goat, the Troll family are forced to leave their native Norway and make a new home somewhere else. Unfortunately they choose the quiet suburb of Biddlesden. Faced with the prospect of 'Baked Beans' for dinner, and the awful spectre of 'The Shower', things are going to get ugly (and possibly hairy and smelly, too). But worst of all, they have moved next door to the Priddle family. Big mistake.

When the Trolls move next door to the Priddles, both families find the other strange, which causes many misunderstandings.

When the Trolls and their neighbors, the Priddles, go off on vacation at the same time, both families are in for some surprises, including a wild, sheep-devouring beast and a scary local mystery. Simultaneous.
