Other Mudokons that escaped RuptureFarms like Alf and Buddy no longer have their lip-stitches, yet Abe has retained his. Why is this?
The Mudokons certainly do have the technology to snip the stitches off, but Abe has decided to keep his as a reminder of the Mudokons’ dark history, of his own unfortunate past, and as a symbol of what will happen to his people if he ever fails his duty to Oddworld. They also have a kind of nostalgic value to them.
