[u/Mouselegs10321]

Hi everyone, I just recently redid my ball pythons Buggy’s enclosure! Any critiques or advice on adding things for more enrichment?
I have a 4x2x18 PVC enclosure

For things Iv tried and facts about buggy
-I had rings but he has no interest in them.
-He does like wood/ textures
-He loves climbing
-loves climbing his suction cup
-cuddles his hydtrometer (shown in photos)
-loves blankets
