He has an escape hatch just down inside the corner cavity of the block retaining wall, not far away from where he's mostly basking in the sun on top of, and right close to my back-door.
I believe he sun-bakes during the day to re-charge the batteries, and that he might then go night-stalking for slugs and snails. The block retainer walls used to be a haven for tiny slugs but I doubt they ever get to grow to 'big slugs'. I've never seen them at least, nor a snail; and I like to think he's out there patrolling of a night.
As the colder weather moves on into Winter, the blue-tongue will disappear back into the wall, or some other chosen place perhaps, to hibernate until around September, October when I'll get to see him again, the next year perhaps.
