Aquamanatee

"Marlow the manatee isn't exactly superhero material. He sleeps a lot, eats a lot, toots a lot, and has never ventured out of his safe saltwater bay. And yet Marlow dreams of being a hero like Aquaman! But when a series of unlikely events leads to Marlow gaining superpowers and not only meeting his favorite hero but becoming Aquaman's sidekick... suddenly Marlow isn't so sure he's ready for his dreams to come true. Could an awkward, blundering super-powered manatee be the best man-atee for the job?"--
