He was switching hides so I took the opportunity to get pictures of his eyes. It's very hard to tell in pictures, as it's only really noticeable in person.

Weird though- right when I opened his enclosure he just immediately tried to get out - which he did (it's not very hard for him to escape once I have the door open since he's so huge). He's still trying to get our right now, actually. Weird behavior after hiding nonstop for 3 weeks.
