Who is who?

All of my childhood I wanted a bullfrog friend. My mom brought me tadpoles two years that yielded the bullfrog I call Leo. This year, there are three bullfrogs in my small pond. Two are always together and this one is always alone. I no longer know who is who. Last year I could tell them apart due to size. This year, they all look the same. I love having them as neighbors.
