A fable about friendship that encourages reflection on identity and how we access knowledge.

In a pond, near the forest, lived two inseparable friends: a little fish and a tadpole. The little fish couldn't believe that the tadpole had turned into a frog, so they argued and argued until the tadpole decided to go explore the world. Upon his return, after telling his friend about the extraordinary things he had seen beyond the pond, the little fish also decided to follow in his footsteps. But he soon discovers that living on land is not what he imagined...

In Fish Is Fish, themes present in other Lionni books appear, such as the importance of friendship or the acceptance of difference. However, other profound aspects are treated in an original way: how we know things, how we know what we know, how we see others, or how we are seen by them. An interesting starting point for a conversation about our abilities and what it means to be unable to do something that others can.
