what other enrichment can I add to his enclosure? 🙂

Hi! Got my ham about a month ago and wondering what other enrichment I can add to create clutter? It’s 48 x 20 in. There’s about 1 inch of bedding hidden by the wood at the bottom btw. I want to add more dig boxes but I feel like the sand bath takes up so much space. Debating whether to take out some bedding, put the bath and then the wheel on top. Thoughts? 🙂
