Mutant FUN Costumes Teenage Ninja Turtles Leonardo Infant Costume | Nickelodeon Costumes Green/Brown/Blue

Baby Turtle, Big Leader Energy
Your little one might not be leading a ninja squad (yet), but they are crawling with purpose and demanding snacks on schedule—so honestly, they’re halfway there. This officially licensed TMNT Infant Leonardo Costume brings the turtle power in a soft, cozy package designed for the tiniest hero in training. It's cute, comfy, and ready to take on Halloween, nap time, or an intense baby bottle stakeout.
Blue mask. Big attitude. Zero fear of pureed carrots.
Design & Details
The costume includes a zip-front onesie made from soft minky fabric that’s gentle on baby skin and strong in turtle style. The printed details feature Leonardo’s signature turtle abs, his blue knee and elbow wraps, and a brown belt with a bold “L” front and center. The mitts are attached to the sleeves to keep tiny fingers warm and looking ready for ninja moves.
The hood has printed eyes and Leonardo’s classic blue bandana, complete with side ties that say, “I came here to lead and then maybe nap in a pile of blankets.” A soft, dark green shell attaches to the back of the suit with hook-and-loop fasteners and gives full turtle-back coverage without weighing your baby down.
Turtle Tot in Charge
From photo ops to first Halloweens, this costume turns your little one into the most responsible member of the sewer squad. It’s soft enough for cuddles, easy to zip on, and fully equipped with Leo’s signature look. The only thing missing? A tiny katana—and let’s be honest, you probably don’t want them holding one yet.
