In January 1992, a cargo of 29,000 plastic animals fell into the North Pacific Ocean.

For over twenty years, these little animals have been traveling the seas around the world, from Alaska to Hawaii, and from the coasts of America to Japan, providing environmentalists with valuable information about ocean currents and the routes trash takes while floating.

In this stunning and amusing story, illustrated with the unique technique of children's favorite picture writer, Eric Carle takes his readers on an exciting journey of discovery.

By following the yellow ducklings across all corners of the earth, young explorers can understand simple directional and orientation instructions and become familiar with basic mathematical concepts.
