Ace opens up a peanut butter jar without reading the warning label on the top... and unleashes a genie! Ridge is more than happy to grant wishes, but warns Ace that every wish requires some sort of sacrifice. The year's supply of peanut butter sandwiches comes at the cost of Ace wearing a smudge of peanut butter on his cheek for a year... and he gets all of the sandwiches at once! Even though they are individually bagged and will magically stay fresha a bit longer, this is not exactly what Ace meant. Ridge tells Ace that he must accept a quest or all of the cats and dogs in the world will turn into zombies. His quest is to find Thackary Anderthon and stop him from finding the Undiscovered Genie, who grants wishes that have no consequences. He can make wishes related to this quest to help him, but the price is usually high. (He does say no to replacing his legs with Pogo sticks-- permanently!) His quest becomes even more complicated when he meets fellow Wishmaker Tina and her genie Vale, and Tina's quest is to save a former Wishmaker... who happens to be Thackary Anderthone. When the quartet meet Thackery's son, Jathon, whose quest is also at cross purposes to the others, the trio start to wonder exactly how they can save the universe. They must travel all over on bizarre quests in order to stave off either the zombie pets, the constant raining of pianos, or the other terrible fates that could befall the world if they are not successful in figuring out what the universe requires of them.
