Wallace & Gromit is an arcade platform adventure where the player has to liberate the zoo from the evil clutches of the maniacal Feathers. Feathers wants to make diamonds. Lots of diamonds. And he'll stop at nothing to achieve his dream. The diabolical penguin has incarcerated all the baby animals in order to persuade their parents to do his bidding and manufacture gems from the coal being mined using the incredible diamond-o-matic. Wallace & Gromit have smelled the fishy presence of Feathers and developed an elaborate plan to infiltrate his domain. And so the indomitable duo has to construct the integral part of their scheme, the Trojan Penguin. When the giant wooden bird is placed at the zoo gates Feathers' narcissistic personality embraces the 30-foot tribute and makes it the zoo centerpiece. Unbeknownst to Feathers, Wallace & Gromit reside in the Trojan Penguin complete with resplendent standard lamp and armchair. At night the pair can start their amazing adventure.
