Dr. G. Romero

 George A. Romero or Dr. G. Romero on Poptropica is a creator of popular horror movies. He is seen in Zomberry Island as a professor trying to find a cure for the Zomberry plague. On his break, he drinks a Caribbean Madness smoothie, and turns into a Zomberry himself because of the blueberries inside the smoothie.
