Teenage Mutant Ninja Turtles Donatello Infant Costume

Tiny Tech Genius in a Half Shell

Cowabunga, baby! The Infant TMNT Donatello Baby Costume brings the brains of the Teenage Mutant Ninja Turtles straight to the nursery. This officially licensed outfit transforms your little one into Donatello, the cleverest turtle of the bunch—complete with shell, mask, and all the turtle-powered charm needed for a totally radical first Halloween.

Snuggly Soft, Totally Turtle

Crafted from plush, minky fabric, the onesie is as cozy as it is crime-fighter chic. The front features printed armor details and Donnie’s signature “D” belt, with purple rib-knit cuffs to keep things snug while crawling or cruising in the Turtle Van (a.k.a. the stroller). A front zipper makes for fast changes when it’s time to swap superhero duty for a nap.

Turtle Hands and Techy Toes

Attached at the wrists are soft, three-fingered turtle hands for a full ninja look, while the foot covers slide over your child’s feet to reveal the classic TMNT two-toed style. Whether your little Donatello is kicking back in the lair or showing off their ninja moves at the costume party, every detail is designed for adorable authenticity.

Hooded Hero with a Built-In Mask

The hood tops it all off with Donnie’s purple eye mask printed across the front and a playful fabric bandana knot at the side. Around back, the detachable dark green shell connects with hook and loop fasteners, featuring printed texture to mimic Donatello’s armored design—perfect for when baby’s ready to roll into action. Brains, bravery, and baby giggles—this Donatello costume brings the Turtle Power in the cutest possible package!
