Hint: Rayman 2 reference: 
In the Hoodlum's factory, get to the place where you have to jump across crates 
to get to the other side. Once there, keep going up. You will eventually reach a 
location with a switch to activate the lifts to get to this second "conveyor belt". On 
those lifts, get pretty well up to the top. There is a hole in the side of a 
huge "pipe". Jump and helicopter over there and go in. You will see some of the 
villains from Rayman 2, including Admiral Razorbeard and his other cronies.
