By day, Greg told Connor and Amaya that they always look after him because he's the youngest, but he says that he can do things by himself. But when they're about to go home, the school bus is mysteriously missing. By night, it is revealed that Night Ninja and his Ninjalinos have stolen the school bus and wants to convert it into his own Super-Vehicle. The team tries to get it back, but a stubborn Gekko insists on completing the mission by himself, which only made Catboy and Owlette annoyed with him.
