I was the sound designer on the game version of Looney Tunes: Back in Action whilst working at Warthog Games.
Looney Tunes: Back in Action is a platform game developed by Warthog Games and co-published by Electronic Arts and Warner Bros. Interactive Entertainment in 2003 for PlayStation 2GameCube, and Game Boy Advance
It is based on the movie of the same name by Joe Dante.
The game share its plot with that of the movie. When a mystical gem called "The Blue Monkey Diamond" is stolen from Daffy Duck by the Acme Corporation, the Looney Tunes must set off on an adventure to get it back
Gameplay involves playing as Bugs Bunny or Daffy Duck. Each character has their own unique special abilities and the game requires using both characters. 
Along the way, money is found all over the place, usually as coins and bills. Gold bars are also found but rarely. 
Coins are worth $5, bills are worth $50, and gold is worth $100. Some items are buried in the ground. The money is used to access any of 4 other regions in the game such as Vegas or Paris. 
Each character can take 3 hits. Upon the third hit, they return to the last checkpoint. 
There is an unlimited number of lives. Bugs Bunny has the special abilities of digging and double-jumping. 
Daffy Duck has the special abilities of fluttering and swimming. Bugs and Daffy must accomplish four to six challenges within each of five regions.
