Footfoot and Lizinator, there were 2 of them and the female was digging a hole for herself... we guessed either to lay eggs or just to keep cool.

Knockout, that's what I was hoping to find some info on, but when I tried searching I mostly came up with stuff about the 2nd amendment.  I was hoping maybe someone here would have better searching skillz?  It was really heartbreaking.  And surprising seeing how most of their other animals had adequate enclosures and seemed quite happy.
