I’m sure Noodle will love the sand bath when the sand arrives, do you have a platform to put it on, they need a good size sand bath with a couple of inches or more of sand so it’s quite heavy & needs somthing to support it. They do like it to be partially covered to if you can do that, you could use cardboard, a bridge or cork tube maybe.
I’m hopeless at thinking in square inches! What are the dimensions of the bin?
I’m not sure but I think 600sq inches might be a little on the small side but you’ve got a nice amount of substrate in there & he should be able to have a good dig & burrow a bit in that.
Which wheel do you have, I can’t see clearly through the bin.
