Mega Havoc 3
Mega Havoc III is a bonus area in the Game Boy Advance version of Rayman 3 found in the Magmacosm world.
Level
It has the same environment as that in River of Fire and there is only one stage. In this stage, you have to ride over rivers of fire on plums. There are blue lums to be collected to fly over pits of lava, avoiding spikey helecopter bombs and hitting the regular helecopter bombs that are in the way to pass through. There are 20 Yellow Lums here to collect, though as this is a bonus level, there are no cages to be found.
