Tort enrichment

[Jimbo0525]

I have a juvenile eastern hermanns and his cage is somewhat bare, I have water and food dishes and humid box and a non humid hide for him and a hill made of dirt in a corner, he seems to like climbing on top of his hides and going on top of the hill but I worry he could fall off of his hide. What are some good enrichment items I could buy for his cage to make it better for him
