I like your idear about comical Mudukons... I think it would be cool if charictors interacted with there emotions more.
I also wonder if all creatures on Oddworld will have emotions?... I mean surly Mudukons aren't the only emotional beens on oddworld.
Heres a idear... maybe if you are playing as Munch and you talk to Abe using game speak his responce depends on his health and emotional status... or vice versser if you are playing as Abe.
