Nickelodeon's traveling family takes center stage on the Game Boy Advance in The Wild Thornberrys: Chimp Chase. Spanning the globe and four levels with three stages each, Eliza and her family set off to rescue Darwin, who has been kidnapped by those poaching derelicts Kip and Biederman. Playing as Eliza in all but two levels, the side-scrolling action moves from South America to Australia in search for Darwin.Beginning the game as Darwin, players make their way across the jungles of South America, eating cheese crunchies and swinging from vines. At the end of this first stage, an unsuspecting Darwin is kidnapped to be an exhibition in a zoo. In stage two, Eliza takes over and the search begins. Avoiding falling from trees and vines, as well as obstacles such as snakes, bees, and lions, players must guide Eliza through a South American jungle and a spooky temple, then on to the African plains, the Arctic Circle, and finally the Australian Outback. Each continent level contains three stages that must be completed before the level is won.
