Sammy is the most un-sloth-like-sloth that you'll ever meet! He is always busy and excited but today he can hardly contain himself. He's having a sleepover at the museum with his friends and has so many things planned, from treasure hunts to midnight feasts! But when someone tries to sabotage the sleepover, it's up to Sammy and his friends to work out who is causing trouble. And does it have something to do with Clive the tutu-wearing chihuahua... ?
