In Leo Lionni's wonderful story 'Fish is Fish' a tadpole and fish enjoy being friends until one day, the tadpole notices he has started to change - small legs are forming, his tail is shortening. The fish is perplexed - how can this be? The tadpole had been a 'fish' like him, now he was a frog! The frog decides to explore the wider world and crawls out of the pond leaving the fish behind. The fish often wonders what has happened to his friend - and then one wonderful day the frog returns to tell the fish about the wonderful things he has seen - follow the link to see how what images of birds, cows and people capture the fish's imagination! The fish is inspired to explore the wider world as well. Lionni writes, 'with a might whack of the tail' the fish 'jumped clear our of the water onto the bank'. But of course, what happens to a fish out of water? Thankfully the frog is nearby and able to push the fish back into the water. The fish decides the pond is the best world of all and this is where he will stay.
