Nice :) But still, there is a bit difference with or without the umlauts on the o's:

there's gombóc (=dumpling), probably from gomb (=button, knot) plus diminutive,

and

gömböc, from gömb (=sphere) with diminutive. "Kis gömböc" is the "meatball" that eats up everyone, until he bursts, in an old folk tale, probably the source of the name here. Ultimately I guess both words are from the same root.
