Teenage Mutant Ninja Turtles Infant Donatello Costume

The Smartest Turtle in the Playpen

Your little one might not be building gadgets (yet), but they are working on advanced crawling techniques and babbling in mysterious code. Sound familiar? That’s baby Donatello energy. With this officially licensed Infant TMNT Donatello Baby Costume, your mini genius is ready to join the Turtle squad—just with more naps and significantly fewer nunchucks.

Perfect for litte fans of brains over brawn, snack time over sewer time, and anyone who's ever tried to eat a crayon in the name of science.

Product Details

This soft and cozy onesie is made of minky fabric that’s gentle on baby skin and easy on grown-up patience. It zips up in the front for quick costume changes and features a printed turtle shell on the front, complete with Donatello’s iconic "D" belt emblem. Purple rib-knit cuffs add a snug and stretchy fit, while attached turtle hands at the wrists bring full cartoon commitment.

The matching hood is topped with Donatello’s printed purple mask and a tiny fabric bandana knot at the side—because every baby genius deserves their signature look. The attached soft shell on the back has printed detailing and connects with hook and loop fasteners, making it easy to remove when it’s time for snacks or diaper duty.

Foot covers slide right over baby’s feet and feature the classic two-toed TMNT look, turning your tiny human into a full-on ninja turtle with zero training required.

Dangerously Cute Donatello

Donatello might do machines, but this version mostly does milk breaks and surprise giggles. This costume is equal parts adorable and totally radical, ready for crawling into action and stealing every ounce of attention. Cowabunga comes in many forms—and in this case, it comes with chubby cheeks and turtle feet.
