Enjoy cosplaying your favorite cartoon character from the story of an 11-year-old suburban boy, his "super-genius" 13-year-old twin sisters, and their talking dog. Make yourself a "test" subject of cosplay, just like this character who is often used as a “guinea pig” for his sisters' exceptional scientific experiments! Imagine embodying this mischievous and unpredictable cartoon character with our costume bundle that includes a green unbuttoned shirt, a black t-shirt with a trefoil radiation sign, and of course, his trademarked olive color Super Smarty Pants. The only thing missing? His hair, of course! Mimic his blonde hair with reddish-orange ends by grabbing a wig. Be it Halloween or a cosplay convention, this recognizable costume is sure to pass the test!
