Watch out—Mr. Hammerhead is coming through! 🦈

Dive into a colorful underwater adventure with Mr. Hammerhead and his ocean friends in this playful picture book created for little readers who love sharks, sea creatures, silly stories, and big imaginations.

Watch Out, Mr. Hammerhead! began more than 20 years ago as a silly song written by D. R. WhaleTail. Years later, he re-recorded the song with his children—and that family favorite eventually swam off the page and became a book.

Filled with bright ocean illustrations, humor, and an unforgettable hammerhead shark, it's a fun choice for story time, bedtime, classrooms, ocean-loving families, and young shark enthusiasts.

Perfect for:
🦈 Kids who LOVE sharks
🌊 Ocean and marine-life fans
📚 Read-aloud and bedtime stories
🎁 Birthdays and holiday gifts
🐠 Aquarium-loving families
🌺 Families looking for an independently published Hawaiʻi-created children's book

The silliest shark in Hawaiʻi — now in book form

Watch out — here comes Mr. Hammerhead! What began as a silly song kids couldn't stop singing is now a rhyming picture book: a big-hearted swim through a Hawaiian reef, with friends to meet, facts to pocket, and a chorus that sticks in your head (in the good way).

Made to be read out loud — all the voices encouraged. Along the way, young readers pick up real hammerhead facts woven into the rhyme, so the giggles come with a little shark school on the side.

You'll also find Mr. Hammerhead in person at the Waikīkī Aquarium Gift Shop and Kona Stories here in Hawaiʻi.
