Two polar bear friends have a thrilling adventure as they imagine solutions to a variety of possible situations; their story will show readers how to create their own tales in response to the question "What if.?" in this ingenious picture book. "What if . we got lost far, far, far away, and couldn't find our way home? Then we would become the bravest explorers in the world." So begin the adventures of two intrepid polar bears. Traveling on a ship imagined from an iceberg, the bears encounter magnificent sights and scary situations. When a city made of crayons melts, the bears use pencils to create a beautiful gray world. When all the words in the universe disappear, the bears invent their own language.

When something really big and really scary happens, they whistle and hold hands until it's not as big or scary anymore. And when they find their way back home, they're ready to imagine a thousand more possibilities. This companion title to the Boston Globe-Horn Book Honor Book One Day, The End . is ultimately a book about imagination, friendship, and finding possibilities in the smallest moments.
