The Snail and the Whale By Julia Donaldson
This beautifully illustrated rhyming story tells about a snail who longs to see the world. A whale takes the snail on his tail to see fiery mountains and golden sands, towering icebergs and far-off lands. Seeing these grand things makes the snail feel very small in this wide world. Not until the whale ends up getting beached on the shore does the snail realize that she too can be important. She helps save the whale and this tale of friendship has a sweet ending.
