Toilet Bowl Decoration

Yet another thing I've gotten accustomed to while living remotely....these frogs in my toilet! Since it's winter here, daylight starts around 7:00 and usually I am up before then, which means it is rather dark when I wander into the toilet for my morning pee. I opened the lid and as I was sitting, something clicked that there was a dark spot inside the toilet......What if this had jumped up and hit my butt? I would have freaked!  ha. (which would have been hilarious as an after-thought.) I scared him, He scared me, so he plopped back down into the water and swam away to ???
