how come when Abe says hi to a slig the slig says hi back? and why do modokens kill them selvs when theair sad and you hit them I must know!!!.........well not that bad. Try a slig sig.
Sligs are social creatures, and their jobs don't exactly allow them to mingle with slaves or other guards. If a Slig recieves a greeting, he'll swing it back with pleasure. Sadly, GameSpeak isn't complex enough to get a conversation going.
Mudokons are emotional creatures. The blue Muds in Abe's Exoddus aren't merely sad - they're actually depressed. One too many nasty surprises, and these poorly chappies will become suicidal. That means trying to kill themselves.
Max beat me to the answer this time. He's right, just becuase sligs are sadistic dosn't mean they won't return a friendly greeting (until they realize it is the terrorist mastermind Abe and blow him to bits).
P.S. Just in case you didn't know, there is a Q and A thread lurking somewhere in the general discussion topics. Ask your questions there instead of posting a new thread.
