The Octonauts are a crew of adorable animals who explore the oceans in search of adventure and fun! From their undersea base called "the Octopod," the Octonauts explore a vibrant world full of thrills, chills, and gills. The crew of eight talented critters, which include Captain Barnacles, Kwazii Kitten, Peso Penguin, and Professor Inkling, is always ready to embark on a new exciting voyage.

The Octonauts travel to a large reef city where they discover this bustling destination has turned into a ghost town! The once colorful coral has turned an eerie white and homes lay empty. So the crew visit different reef 'neighborhoods' from mangrove forests to seagrass meadows, searching for clues. Can they solve the mystery of the great ghost reef? Find out!

Combining the instant appeal of Hello Kitty with the intrepid spirit of Jacques Cousteau, the Octonauts will entertain and delight children, while adults will appreciate the stylish design and subversive humor. Lushly layered and brightly colored illustrations create a teeming undersea universe that will dazzle readers' eyes, inspire their imaginations, and tickle their funny bones.

Called "charming and beautifully-designed" by comics scholar Scott McCloud, Meomi's winsome cast of characters have attracted an international audience, from kids, parents, and teachers to digital artists and fashion designers. What is their next mission? Stay tuned for the next Octonauts adventure to find out! Immedium's original four books inspired the popular animated television series that is broadcast on Disney Junior and Netflix and in more than 100 countries around the globe.

"I've had the pleasure of reviewing all of the books in Meomi's wonderful 'Octonauts' series, which are published by Immedium. I have to say, they just keep getting better and better, and the newest, The Octonauts & the Great Ghost Reef is probably my favorite yet. Not only are the illustrations so cute I want to hang them on my walls, but the story is great, and it's educational... Every page is filled with the cutest illustrations, featuring Meomi's signature characters!"
