I read it, too. I bet it was some sort of tree frog. We had lots of them in various outdoor
spots when we lived in Florida. They especially liked to hide behind the shutters and hang out in a bird of paradise tree. They made quite a racket when it rained. Only one I saw inside was in the toilet of the pool bath that was seldom used. My grandson was six when he visited and happened upon it. He was not amused and he wouldn't go anywhere near that bath for the remainder of his visit.
Your account made me laugh, I searched my history also, alas, it wasn't there.
