Teenage Mutant Ninja Turtles Adult Donatello Costume Onesie | Nickelodeon Costumes
Suit up as the brainy hero with the Teenage Mutant Ninja Turtles Donatello Adult Costume Onesie. Officially licensed by Nickelodeon, this comfy look lets you channel Donatello’s gadget-loving energy without sacrificing a stitch of comfort.
Crafted from soft, low-pile minky fabric, it feels like lounging in superhero pajamas—perfect for long movie marathons or casual cosplay. It zips up the front and features rib-knit cuffs at the wrists and ankles for a snug fit that won’t hinder your gadgets or pizza runs.
The printed design shows Donatello’s turtle chest emblem, purple elbow and knee wraps, and a brown belt with the D front and center so there’s no mistaking which turtle you are. The attached hood completes the look with a printed purple bandana, eyes, and tiny side ties that nod to the iconic Turtle Van.
Whether you’re heading to a party, a comic-con meetup, or a cozy night in, this TMNT Donatello onesie blends clever styling with everyday comfort. It’s an official, easy-to-wear costume that fans will love for years of heroic lounging.
