yeah, munch is always protected by the crane cage or something like that.
anyway,

my funny moment was when after i finished the scrabainian nests, i backtracked to the part with those two scrabs and those elevator traps. the traps magiclly reset themselves, so i mess with the scrab on the bottom. i was wondering where the scrab on top was so, i climbed up there (little did i know that he was standing there in the shadows). a while later, the scrab suddenly appears out of nowhere and tries to kick my ass (litterally) but i wont die. as soon as i step through the big door all you hear is over lapping 'uha' and he finnally dies. same thing happened when i activated the invincibility cheat in the mudomo vaults: every time i ran into a paramite with his jaws open, abe skids and goes uha 8 times before going back to normal. IT WAS HILARIOUS!!!!!
