Oh man, so I got all these cool plant vines and climbing branches with suction cups beforehand ONLY THEY DONT STICK TO my AP PVC lol (I'm going to try and see if maybe hot glue works and I'll just have to re-glue after every cage clean)
but I got this really cute one that you can find at Petsmart (I just cry in the corner bc I haven't been able to use it yet lol).

Reptile hammocks or those little wooden bridges (like what Maze has) you find for rodents are also good choices (just make sure the wood is reptile safe and you may wanna pretreat to be safe)
If you want more of a diy approach you can always use pvc pipes you find at Home Depot/lowes and make your own jungle gym.
also a note about woods. If you want to have them last longer and less prone to mold I recommend using sealant on them. Just make sure it's non toxic/low voc, water based and at the very least water resistant. Water proof being best of course.
