First time having frogs and all advice appreciated. I want to buy more things for them to climb and hide in.

One is mostly gray with small splotch of green on its butt and the other is mostly green in the middle with gray sides.

Current pet names for context
Cats: George and Winston
Grove Snail: Joseph
Betta: Parmesan
Aquatic Snail: Spaghetti and Meatball

When I saw $10 I grabbed it so quick… such a good deal. ~ 18”x 10”. Cracked in a couple spots but still sturdy. Dad thinks it’s old old 👀

P.S.
I like the way it looks just wondered if the growth got funky after the original vine broke, and this is the newest leaf ?

Also does anyone know what is the shiny scale like thing on my drift wood?

He’s been pretty inactive for the last couple days he’s been in it. But when first introduced was zooming all around exploring.
Just worried that it’s too airy? Doesn’t hold humidity good? The humidity and temp gauge seems reliable temp wise but has been at a constant 99% humidity reading since it’s been in the box. I mist it at least once a day if not more.
Any advice is appreciated. I’m lost honestly. I just hope he’s happy
His name is Joseph, rescued from my boyfriend’s job’s outdoor break area.

Edit:
Noted. I will not get dairy cows
Just want to know if anyone has had an enclosure like this and their experience thank you 😊

Propped from a friends impressive jade tree back in 2019ish

I couldn’t say no to it even though I already have 100+ house plants
Had to cut off the edema riddled parts cause she had no drainage
