HAHA! I never ceases to amaze me what interesting new places they will find to hide in the same old enclosure. Mine is fiberglass and opens from the glass front and my girl can actually fit in the lip that surrounds the glass front. One day, she vanished, and I panicked, even though the glass was still closed and then I saw this little face and flicking tongue coming down from the top of the tank. haha! As long as she stays on the inside, she can scare the crap out of me however she wants.
