Gaby is now thoroughly enjoying burrowing and tunneling. When I woke up today morning, I found a little tunnel she burrowed along the glass wall, some 5 inches below the surface. It just melted my heart and happy cried a little seeing how much she loves it now.
I was reviewing all the pictures again, and realized one of the burst shots produces this beautiful gif of Gaby sticking her head out from beneath the substrate. (Hover over/click on thumbnail to animate gif)

I haven't had time to process and upload the video of Gaby burrowing. I will try to put it up soon though.
