Lol sounds like my boy hognose. You walk into the same room and he's bashing his face against the tub at you, putting up quite the show.
Are the chin markings more of a spider thing, or do other morphs have them as well? I mean it makes sense I haven't seen it except for on this snake in person.. since everybody takes photos of belly shots or top shots all coiled up. Chins aren't typicallly a priority for photos.
