So my baby albino love to partially or completely bury herself in the aspen substrate. Being albino it sometime bakes it hard for me to find her since she blends in with the aspen.
Feeding is interesting too. Last time, she stuck the mouse with only her head sticking out of the "sand." LOL.
I've read that some RTB's will do this while they're young. But an albino doing it on aspen certainly brings it to whole new level of hide-n-seek.
