>>55674750Most of Glaceon's dex entries mention it controlling its body heat at will, specifying that it "can" freeze its fur or "can" freeze the surrounding atmosphere to make snow and ice.
The idea I've got in my head now is that a Glaceon's default temperature would be similar to an inorganic object in the same location or a bit colder, except that you couldn't warm them up noticably with your body heat.
