Ha haarrrr me hearties, the band are off on a pirate adventure… which isn’t actually their intention. They just want a well needed holiday using Cousin Mac’s new invention, a portable holiday destination generator. It’s not working particularly well as they get stuck on a deserted island with a donkey and a palm tree, only to be picked up by the world’s friendliest pirate, Yellowbeard. He has his own problems as his treasure has been taken by the meanest pirate of them all, Ruthless Ruth. So the band simply have to help him…. off to Skull Island!
