Pizza Pete and his dad's magical pizzas are selling like hot cakes, until something goes wrong with the Shrink potion and Anna stays shrunk. EEK! Pete and his friends must track down the elusive creator of the magical potions, Professor Tregoning, to get help. But Team Useless has a lot to juggle - a road trip, a talking dog, too many puppies to count and a large dollop of out-of-control magic! Can they find the peculiar professor before her evil boss, who has his own terrible plans for the potions?
Team Useless must pull off their biggest mission yet, or Anna will have to stay tiny... for ever!
