If you are in two-player mode, one of you should collect all the spirit balls until becoming the beast, as that player can now protect the other player until he can turn into the beast.

Avoid the blue demons by jumping over them or onto a higher level. If Nelf himself appears to rise up and you are in one-player mode, rush into him to get the end of level baddy. Just hold the 'Fire' button down and face him for the best results.

The main problems here are the jumping head-eaters. Kick or low-punch them when they're on the ground. The rattles of the snakes should be kicked to destroy the snakes. The end of level baddy is no problem. Go underneath the dish spewing out eyeballs and put on the autofire.

The main problem on this level is the mass of running chickens. Stay in the middle of the screen near to the top if possible. When you become the beast, keep pressing 'Fire' to keep somersaulting as long as there aren't any holes.

Only use your breath on the end of level baddy. Keep pressing 'Right' and 'Fire' to breathe on it. After it has moved in a bit, follow it and repeat the above procedure to kill it.

When you become the beast, use ducking punches instead of the special weapon. When you come to the Nelf-created creature, go to the far right-hand side of the screen and hold down 'Fire'.
