Sure, But this should be in the err... Help section. (Xavier! Shoot, he ain't here. Alcar?)
Okay here goes,
First make sure you have some grenades. If you have no grenades you need to get them from the Boom-Machine (top-right).
-To get grenades from the Boom-Machine, make sure you stand on the top-ledge. Then wake the slig up. He will walk off the screen later.
When he walks off the screen, jump down and press the button on the Boom-Machine. Then run back up to the ledge before the slig returns. When he is away again, jump down and get the grenade. Then run back up to the ledge again.
-Okay so now you have grenades. Walk to the left(top-left screen) and stop at the end of the ledge. Now get ready to throw a grenade to the left. Wait until you hear the 5th beep sound, and then throw the grenade to the left.
If correct, the grenade has blown up the anti-chant-prossesor.
Now chant to posses the slig underneath you.
Make him walk to the right and shoot the other slig.
Explode him.
If correct you can pass that piece of the level now. And I won't spoil the rest of the level for ya, unless you need help with that too.
I hope that makes sense.
It's too hard this....
I wish I could tell you something that would help, but I don't know how to fix that.
