After I got the plunge (in milkman's level) and went outside the building, I got grabbed by some creature and pulled under ground. I defeated the creature severeal times, but every time it ressurects. I tried to escape while it is "dead", but couldnt find any exit from the room.
any suggestions..
First, you can get a hint from Ford Cruller by using the bacon from your inventory. Try that first.
Solution follows:
Once you've defeated the creature, you're still not done - obviously. You need to use telekinesis with one of the heads and throw it into the headless corpse of the ...thing.
Did that startle anyone else when they got pulled under? I jumped because it seemed pretty random to me, but I guess it makes sense and all.
