The superpower cans make a reappearance in Rayman: Hoodlum's Revenge, except...well, the powers they provide are different.
Here are the ones I know of so far (in Rayman: Hoddlum's Revenge):
Blue can = Throttle Copter (Ok. Doesn't it normally give you Lock-Jaw?)
Yellow can = Heavy Metal Fist (??? But the yellow can gives you Throttle Copter)
Red can = Fire Resistance (Now this is just stupid. The red can is supposed to give you Heavy Metal Fist)
It is really confusing but at least they are in a GBA game. They aren't in the GBA version of Rayman 3.
Weird.
Jockjaw: an amazing andseemingly alive weapon for latching on enemies and giving them a nasty electric bite!
Shock Rocket: a funky torpedo that causes mighty blows. You can control this rocket too.
Heavy metal fist: Pratically the strongest powerup and cause mighty blows with spiked knuckle sandwhiches lol.
Vortex: You can make hoodlums spin and go smaller. It's so funny!
Throttle copter: Though it allows you to fly, if lasts for three seconds at least.
