This is a surprisingly awesome question because we would generally make the "fancy word" for something-shaped by sticking -oid or -morph onto the ancient Greek or Latin word for the thing, but of course the ancient Europeans didn't have potatoes.

@futurebird Temple.
Example: My body is a temple

@futurebird sleeping-catoid.

@futurebird I've heard "oblong" or something like that.

If you mean the saddle-shaped potatoes deep-fried variety that Pepsi-Cola/Frito-Lay puts in a can, and the less precisely engineered ones of similar shape that everyone else puts in a bag, the word is 'biconcave.' That's not non-binary, so maybe we can all get our biconvex behinds behind it. A full 22% of US potatoes now choose this shape as as the shortest path to our bellies, matched by the fraction of potato-eaters who find it the shortest path around caloric insufficiency, likely to jump with AI-potatoes and the tariff on French fries, and if you think 22% is insubstantial, that's the efficiency of the most expensive solar panels.

@futurebird Ellipsoidal, ovoid, ovaloid, ovaliform

@futurebird patatoïde is one of my favourite French words https://en.wiktionary.org/wiki/patato%C3%AFde
