Thumperino Superbunny and the Pirates of the High Seas is the third installment in the children's book series Thumperino Superbunny by Amber L. Spradlin.

Thumperino is an adventurous house rabbit blessed with super-powers and a duty to make the world a better place. Hollywood Book Reviews heralds it as "...an entertaining, imaginative, and thoughtful adventure story about a superhero with the ingenuity of Sherlock Holmes...something children will enjoy."

Thumperino is assisted in this adventure by his best friend Veronica, a therapy rabbit who lives at the New York Public library. Together the two do extensive studying in order to prepare the Superbunny for his upcoming vacation to St. Kitts. They discover there is a veterinary research school on the island, which may hold secret clues. Once Thumperino lands on the tropical island he soon finds it's not all fun in the sun. Someone is dumping garbage in the sea and it's up to Thumperino Superbunny to get to the bottom of the mess. But his mission may be doomed when he unexpectedly tangles with a band of pirates. Will a surprising new super-power and the skills he learned at the library help him save the day or will he have to walk the plank?
