That was untill Munch Oddysee came along.
Wasn't one of the Vykkers (Irwin) in Munch Oddysee female (she worn lip stick in one of the CG clip)??Heres some infol
profile on them.
There was also the Glukkon Queen (lady Margaret), who makes a indirect apparences also in Munch Oddysee.
There are mention of Sam (Abes mom/Mudokon Queen!!) and Slig queen Skilla (from a post from Sligster).
Theres already a thread about female muds called
Female Mudokon. Seems that there are pictures of them in the Oddworld art book too.
On a different note all creatures in Oddworld do not seem to have a nose.
Or at least no visble nostrils...
