Leo Lionni (1996), Dragonfly Books
In the middle of Rainbow Pond there is a small island where three little frogs live. Milton, Rupert, and Lydia bicker constantly, arguing over who gets what on their tiny island. A large toad appears and tries to get them to stop quarreling, but they quickly forget his request when Milton finds a worm. Suddenly, a large storm appears and soon the water around them swallows up most of the land! The frogs try to cling to any rocks they can find, but only one remains. The three of them share it, holding on until the water recedes. Once the water is gone, they discover that the rock they had been clinging to was actually the toad! Grateful to have made it through and to have their island back, the four of them become friends and no longer bicker about who gets what.
