Based on a cartoon series that ran from 1990-1995, which is about a new generation of Warner Bros./Merry Melodies/Looney Tunes characters.
The 4 years later released North American version is Scary Dreams. The original European versions title tells you who you'll be playing as.
Game Boy Advance (2002, published by Conspiracy Entertainment)
B - punch
Down & B - uppercut(pop-up)
A - partner(you select between 7 characters before the game begins, and if you have a hard time choosing, there's a random "?" selection in the middle. You can keep using them for as long as they have their health bar in the upper right corner of the screen)
Up - jump
Up, A - jump punch(good follow-up for the pop-up)
Down, Down/forward, forward & B - shopping cart push(requires the meter between the health bars to at least read 1. The meter fills up with each attack. The move itself is very damaging, especially if you can pin enemies against the side of the screen with it)
Down, Down/forward, forward & A - partner special(may use up to 3 bars of the meter)
You have infinite continues, but only one chance to make it through a stage. You'll have full health when you transition to a new section(which is also where you'll continue from). As is usual with Treasure, there's sort of a trick to it. You want to make as many combos, or even better, bowl enemies into each other(which the uppercut can do), but for the most part you really want to build that meter for the shopping cart move/partner specials. Like in Astro Boy, some enemies will show up larger and pixelated, which are often the best type to try to bowl into the others.
Babs - will hit a Tennis ball with a racquet. It's a good move to keep enemies at bay from a distance. Her partner special, which only uses 1 special meter, hits a large Tennis ball for extra damage.
Plucky - summons an anvil to drop on top of, and stun enemies. His partner special uses 2 meters, and drops a larger anvil(which can give Buster some extra breathing room).
Hamton - a literal punching bag, you have to try to hit him before the enemies do, so he can constantly be bowled into them. His partner special costs 2 meters, and he'll throw a food item at Buster, restoring his health.
Shirly - Only has the partner special, at the cost of 3 bars of the meter, she will make Busters attacks faster than enemies can react to for a while.
Sneezy - if you can buy him the time without being attacked, will stun enemies for a fairly long time with his sneeze. His partner special, at the use of 1 meter, will stun enemies even longer.
Fifi - shoots a stink cloud that hurts and stuns enemies for a little while. Her partner special, at the cost of 2 meters, will leave a larger cloud that stays on screen a while longer, which is an effective trap to knock enemies into.
Dizzy - provided you keep him from being hurt, he spins in place and hurts every enemy that he comes into contact with. His partner special uses 4 meters, and turns him into a longer vertical tornado that lasts a lot longer.
