The story sees the duo take on Feathers McGraw, the penguin villain from The Wrong Trousers, once more. Feathers has escaped from the penguin enclosure at West Wallaby Zoo, and taken over the entire zoo, kidnapping young animals and forcing their parents to work for him, helping him towards his ultimate goal - turning the zoo into a diamond mine. As Wallace and Gromit delve deeper into the zoo they discover ancient temple exhibits (complete with booby traps), drills, lava, loads of machinery, and even snow slides as they travel about the six levels; in each they must save three baby animals: elephants in the Jungle Exhibit, beavers in the mines, gorillas in the subterranean facility, pandas in the warehouse, polar bears in the Polar Exhibit, and zebras in the factories. As Gromit, the player must use Wallace's bizarre inventions - including the Porridge Gun, Turnip Launcher, Springy Boots, Melt-o-matic and Techno Trousers - to battle Feathers McGraw's robotic minions and rescue the baby animals in typical platform game style.
