If you do the toad home you could make one that has a tunnel going into a hole in the ground,and that would be covered by the pot.I saw it in the 1001 easy garden projects I think. To some degree the toad might like the flooding.I have 2 toads and 2 frogs(in house) waiting for a pond to be built,and I put them in water each day for a good soaking.You could put out a shallow dish near the toad home,and change the water every other day.The toad home is not really needed as long as it has somewhere to hide.
