You know why the Heroes in a Half Shell look so happy on the 100% cotton TMNT Happy Group Black T-Shirt? Mainly because they see you have pizza...and none of your friends are around. Well, I hope you are into sharing because if you don't, I don't think they will share any of their sweet ninja moves with you. Or they will, but not in the cool teaching-you-how-to-do-stuff way. Featuring smirking versions of Michelangelo, Raphael, Leonardo, and Donatello, the TMNT Happy Group Black T-Shirt is one way to show off your favorite Teenage Mutant Ninja Turtles!
