Basically Chrome's parents are weird and if you didn't think his mom's furryness (she's a wolf monster) would affect his skeleton in any way, you either didn't know she was a weird wolf thing, or you didn't really think too much into it. Also yeah the same thing happened to his little sister and his brother (Menice and Crimson), but I was just too lazy to draw them. (Menice would probably identify as a furry if you asked her.)
