Fish is Fish by Leo Lionni

From beloved Caldecott winning picture book creator Leo Lionni, this charming tale of sticking together and imagination shows how powerful friendship can be. Two best friends, a minnow and a tadpole, are practically inseparable until the tadpole grows legs and decides to explore the world beyond the pond. When the tadpole, now a frog, returns to tell his friend of the extraordinary things he's seen, the minnow, now a fish, tries to follow in his footsteps, but quickly finds that land is not what he expected. Friendship truly saves the day in this imaginative tale of a fish out of water.
