Not only has Sam retired to play nursemaid to a baby Sky Troll, the Mouse in Trousers has retired to live a quiet life teaching other young sky trolls how to behave. In their places we now have Samantha, Sam's daughter, who only recently discovered who her father was, and Alexander Mus, the MIT's nephew. They are inheriting one of the deepest friendships there has ever been between two NPCs ... let's hope they can take Power Pets forward, building on their forbears' success!
