So Oliver likes to scratch at the corners to try climb it. And first time I've ever seen him flip over since he was small and used the log. ( thankfully it's thanksgiving and I was home and not at school who knows how long he's be there) Any ideas to fix this.
I would suggest that you trim your plastic liner to just a tad bit above your substrate line, and then possibly put a few small stones, pebbles, rocks along the edge where plastic meets the substrate. Create some variation in the edge and try to use various things to get rid of right angle corners. Just throwing that out there for u to think about.
Put a plant near the corner with a 3" distance from the walls. This will allow him to walk around the plant and should he flip in the corner it'll give him footing to right himself.
Does his enclosure look like a bare patch of dirt? Or like an empty box?
I bet if he had a more stimulating environment he'd cease climbing the wall.
Does his enclosure look like an "empty box" like this... (google photo)
See how it's just a "bare patch of dirt" with nothing very stimulating? That could cause a tort to want to climb out and escape. Bored, nothing else to do.
Now, many people like the enclosure this empty...but if you are having a tort climbing and flipping, I'd try something else (and I'd never keep it like this)
If you make an indoor enclosure stimulating and with obstacles and plants your tort might be less likely to want to climb the walls.
Some of my indoor chambers to hopefully give you an idea.. lots going on. Places to hide, things to walk over, under, around etc..
