>>It doesn't sound like a good idea to me. What about drainage? I don't think the sty will let the water threw. If your talkin about the popcorn type I read that some types decompose.
something. Like, lets say you bought a set of plates and when you opened the box there was a form fitted piece of styrofoam you had to lift in order to get the plates out.
Also, the styrofoam wouldn't be in the water area, just in the area where there was land. Now that I think about it though, I guess there isn't really that much land area anyway so there wouldn't have to be that much gravel.
That's true about the biodegradable styrofoam. Didn't think about that and what if started to fall apart and little pieces came to the surface. Probably not a good thing! Plus, I'm sure there is going to be some runoff water from the toads when they get out of the water area.
Thanks for your help!!
