The Master Has Arrived
Embrace the wisdom—and the whiskers—of the sewers with this officially licensed Adult TMNT Master Splinter Costume. Inspired by the iconic 1990s Teenage Mutant Ninja Turtles cartoon, this ensemble transforms you into the legendary rat sensei himself, ready to dispense ancient ninja knowledge and maybe a few Halloween treats.
Sewer Sage in Classic Style
The costume includes Splinter’s signature maroon robe, complete with twill construction, screen-accurate details, and fasteners that make dressing as effortless as meditation. A matching brown fabric belt ties the look together with classic cartoon flair, while the distressed hemline adds that battle-worn edge expected of a true martial arts master.
Furry, Fierce, and Fully Realized
The pants, gloves, and foot covers are all made from plush faux fur, giving Splinter his soft but scrappy silhouette. The headpiece features a sculpted snout, sharp felt teeth, and long whiskers crafted from Minky fabric for added texture. Minky claws and tail add dimension and detail to the look, turning every gesture and step into a scene straight out of Saturday morning TV.
Feet Built for the Dojo
The oversized foot covers include grey twill wraps to match the animated version of Splinter’s classic footgear. Whether you're leading the Turtles, training in secret, or striking a wise pose in the shadows, these soft, clawed feet help complete the masterful transformation.
Become the Mentor of Mutants
Perfect for nostalgic fans, group costumes, or anyone ready to lead with honor and fur, this Master Splinter costume captures the heart and humor of the original series. Wise, loyal, and just a little bit ragged around the edges—exactly as a rat sensei should be.
