Bill introduces the mischievous Smitz troop. Living on the coastline, they have their eyes on the food and belongings of unwary tourists. Lurking in the bushes is a criminal mastermind - Merlin, the Fagin of the roadside, plotting his next heist. When whale-watchers flock to view magnificent marine mammals from the lay-bys, the brainy baboons are quick to break into every car, checking for anything that will make a baboon-style picnic.
