Infant Teenage Mutant Ninja Turtles Donatello Costume

Tiny Tech Turtle in Training

What’s small, green, and constantly covered in applesauce? If you said a baby dressed as Donatello, congratulations—you’re about to have the best-dressed little ninja in the sewer (or the living room). This Infant TMNT Donatello Baby Costume transforms your tiny sidekick into the tech-savvy Turtle himself, minus the bo staff and with way more pacifiers.

Because every baby deserves a chance to fight crime—right after their nap.

Fun Details

This costume includes a soft, dark green shell that attaches to the back of the onesie with hook and loop fasteners. It has printed detailing to match Donatello’s high-tech style, but is much easier to clean than anything you'd find in an actual sewer. It’s lightweight and removable, making transitions to car seats or cuddle time a breeze.

The onesie itself is made of plush minky material with a printed front shell design and Donatello’s “D” belt right in the center. It zips up the front for easy changes and has purple rib-knit cuffs for a comfy fit that stays put through all your baby's ninja rolls and wiggly moves. At the wrist, soft turtle hands are attached for an extra dose of turtle power.

The hood features Donatello’s printed purple mask with a little fabric bandana knot on the side—instantly recognizable and completely adorable. The foot covers finish the look with a two-toed TMNT style, sliding easily over baby’s feet to complete the transformation.

Genius in a Half-Shell

This costume captures all the smarts and sweetness of Donatello in one snuggly, soft package. From crawling missions across the floor to mid-bottle brainstorming sessions, your little Turtle is ready for action—just don’t expect them to fix the Wi-Fi.
