This Teenage Mutant Ninja Turtles t-shirt shows Michelangelo, Leonardo, Raphael and Donatello riding a wave on a surf board. The turtles are on their way to enjoy a pepperoni pizza. The shirt reads Surf's Up Cowabunga! The Ninja Turtles need to load up on pizza to stay energized while they take on Shredder and the Foot Clan. While screaming, "Cowabunga!", the Ninja Turtles became closely associated with surfing. There was even a 1990 action figure introduced named Mike, The Sewer Surfer. Let everyone know that you are a fan of the lean, mean, green, incredible team with this Surf's Up Teenage Mutant Ninja Turtles T-Shirt!
