Obviousley, the rabbit would drown. They cant swim nor breathe underwater.
you can, if you put water on it
Depends on what "tree" you put in
Make a cardboard box, and put a soft little towel at the bottom, and then put water in a little container, some little veggies and some hay in the box for food; the cute little bunny!
dig a hole and put water in it
A hole!
if it was empty and the hole is away from the water
I suggest digging a large hole and put food, water and supplies at the bottom of the hole to interest him/her
People put in bytes and bits. Rabbits put in nibbles.
From what i know rabbits do
you make a hole and take salty water and put is in the hole and let it dry in the sun
To boil it, better slit a small hole in the bottom of the egg. Then put it in the water.
A hole... a box... a nest of sorts!
