Last year we had frogs the size of dinner plates in our pool every day!! Not just one or two but half a dozen at a time!! They were the most hideous shade of neon green you have ever seen!! We called them mutants. My husband had to make me "wand" long enough to pull the skimmer box cover off so I wouldn't have to get to close to it. I opened it last year and one those **** things was in the skimmer and I thought I'd pee in my pants!!! Like you, there is a giant pond at my next door neighbors' house but for some reason the idiots would rather come up here to the chlorine.
