Going through the game again last night, I was in Gloria's Theater and, by accident, I discovered you can use the Cobweb Duster on the Teleport Creature!
In the level, there's a cobweb just in front of the stage where the Teleport Creature sits. Raz was looking at him instead of the cobweb when I used the Cobweb Duster and the creature's head got stuck to the end of the hose. While the hose was on, his head was stretched out (because he doesn't ever move) and when I shut off the Duster, his head went back to normal and he made those cursing/grumbling noises at me.
It was a funny surprise to say the least.
