Oh wow. What an impressive little critter. How clever!! x)
They always do surprise me.
My little albino rearranges her tank every four or five days, seemingly in response to temperature and light. In the morning hours when the sun begins to come in, she pushes her hide off of the heating pad and against her water bowl on the far side of the terrarium that's shaded, and then moves it back after sunset. It's really odd to watch. She slithers in and then just pushes it over.
