How did I not see this thread?
Congrats! The old moss hide trick LOL! I've been there.
Mine is in shed now too, but I've taken the moss and scattered it in clumps throughout the cage next to hides and corners. It works great to keep the whole cage humidity up.
Boas, still hide as most snakes are pretty secretive but you will most certainly notice they are much busier than the Royals.
The climbing stuff is really cool, and you catch your guy watching you in the room.
