Rayman 3: Hoodlum Havoc Hint: Double Your Points
Try to grab gems and kill enemies while you are wearing a special suit. The points will be multiplied by two. The grapple arm suit has the longest lasting timer, so use that to maximze your score when grabbing gems over long distances, but in a pinch, any suit will do.

Rayman 3: Hoodlum Havoc Hint: Bonus Points from Bugs
There are two bonuses you need to watch for in order to get more points - one is a blue bug that hides fairly quietly in hard to spot areas. All Rayman needs to do is look at it in first person for a while and earn points.

The second bonus is a reddish alien flower that runs away if Rayman spooks it by running, dropping, or attacking. If you manage to sneak close to it, you can earn a lot of points.

Rayman 3: Hoodlum Havoc Easter Egg: Revolution Leader
For those who played Rayman 2, here's how to see the leader of the red Lums in Rayman 3. First, go to The Longest Shortcut. Next, progress until you get to the rising fist-platform. Now go up the purple platform bouncer. Notice the glittering thing above it, hit it with a supercharged punch. This will open a hole near the platforms. Go inside to see a statue of the leader.
