If ‘godabim’ means kidney stones, ‘romzbim’ means kidney beans and ‘romzbako’ means wax beans, which word could mean "wax statue"?

godabim and romzbim share bim = kidney, so goda = stones, romz = beans; romzbako then gives bako = wax. The descriptor comes last, so "wax statue" = (statue word) + bako, i.e. wasibako.
