I have one of these coconut hides and Saturn loves it, he's constantly climbing on it or in it.
HAHA yes, it was gonna be Frisk or Sans (because he's sans fur) but he just seemed like more of a Frisk. And the coconut is one of these!
Amazon sells them! And you can get them in a bundle with other climbing toys and ladders! I will find you a link! https://www.amazon.com/dp/B007PO3AEC/ref=cm_sw_r_cp_apa_i_zrifFbYR2ANWR
This is something similar but it comes with a ladder!
That’s amazing, we were actually thinking of Gandalf too haha. Our cats are named Gary, and Grayson, so we wanted another G name to fit the family.
As for the coconut, I bought a regular coconut without the moss on it for that exact reason you brought up. This is the one I got, and little Gizmo loves it so far:

I believe it’s meant for birds, but it’s just a normal coconut and is the perfect size for him. Then we just put some of this Sphagnum Moss in there for him so we know what it is:

If you use this as your moist hide, all you need to do is mist the moss every now and then, and replace it from time to time as it comes with plenty. I hope it helps and hope little Gandalf loves it if you decide to go down this route!
I purchased mine at petco but there are lots on amazon! I will link a couple here!

For two crabs you’ll need 20 gallons of aquarium space. Mostly everything on Amazon is a bundle for fish, so it comes with stuff like the filter, heater, etc which those you don’t need. I know petco and petsmart both have just regular glass tanks with nothing else, and both of them sell glass lids as well to fit the tanks!
As for toys: a bunch of people’s (mine included) crabs like the coconut huts, cholla wood, and also things like hammocks and vines for them to climb on.
I have something similar to this https://smile.amazon.com/Prevue-Hendryx-Naturals-Hideaway-Ladder/dp/B007PO3AEC/ref=sr_1_3?keywords=bird+cocnut+hide&qid=1555337929&s=gateway&sr=8-3-spell .
I also have live plants on the bottom of the tank (tall bushy with large leaves able to take cresty weight) and fake plants hanging from the walls.

I had one of these and my rattos LOVED it. Quite a few of them made it their favorite place to sleep.
