Octonauts!

Good design comes in all forms. This particular form would be illustration. I think I want this book for Christmas...

The Octonauts is a crew of misfit critters who roam the ocean in search of adventure, treasure, and fun! From their undersea base called "the Octopod", the Octonauts explore a colorful world full of thrills, chills, and gills! The crew of eight talented critters, including a brainy octopus, brave polar bear, daredevil kitten, and scientific sea otter, is always ready to embark on a new exciting voyage.

These designers are good...real good. So good in fact that they won the contest to design the mascots for the 2010 Winter Olympics.
