Thx for the IRL example, although Saturn's Mimas is water ice, which would be unlikely for minmus because of how close it is to its star, as Scott Manley pointed out in one of his videos. Though sense it has a slightly melted look and the solid lakes/seas mabe when ever it was heated it was softer and rounded? still a bit skeptical that it could just be its composition unless u know of a material i dont that would behave at the distance of minmus and kerbin, the way that ice does at the distance of the gas giants.
