The Teenage Mutant Ninja Turtles made a cameo appearance in "Más y Menos" after ordering pizza to a seemingly deserted alleyway near a garbage dump.
They appear later on in the episode and they have stolen all pizzas ever made. They encounter the Titans, and result in a battle with them. The turtles win at first, but the Titans use pizza, and with their energy and goofiness, they defeat the Teenage Mutant Ninja Turtles, and steal their shells.
