Murray is a cat. Murray loves snoozing, fluffy blankets, and peace and quiet. Bun is a bun. Bun loves. EVERYTHING! And together they are unstoppable! SOMETIMES Murray's enchanted cat flap leads to the garden, but mostly it leads to ADVENTURE! And when Murray and Bun travel through the cat flap and find themselves in a land of VIKINGS, they are given a VERY IMPORTANT MISSION: to travel to TROLL ISLAND and rescue Eggrik the Viking - if he hasn't already been gobbled up by the trolls, that is.
