The brightly colored plant (Croton) can cause vomiting if ingested. It was not intended as part of his habitat and, indeed, it took me awhile to figure out how he found his way into it. It has since been placed somewhere less accessible.
One of my females that lives in our bathroom (that is a pink-ish color) sits high up enough that she blends in with the wall (rather than the tile.) I have to climb up onto the toilet seat to find her most of the time because she hides so well!
