Well, the individual organs are tasty; someone probably had the idea of combining them, and adding some plant matter for roughage, to compensate for the constipation you'd otherwise get. And just for the record, it wasn't actually the Scots who invented haggis. They didn't invent porridge or golf either. The Persians invented golf; I can't remember where porridge and haggis came from, though. I think the Romans invented one of them.

And as for wells, I reckon they're artificial; as in not natural features. Why else would they only be where you need them and not in random locations or pop you out over a 2000-foot precipice? They probably harness some natural force (like magnetism or gravity) on Oddworld that Earth doesn't have.
