A Macaroni Penguin looks over a fish themed pumpkin at the Detroit Zoo, Wednesday, October 10, 2018, in Royal Oak, Mich. Each year in October as Halloween approaches, some of the animals receive pumpkins filled with treats to eat during the zoo's annual Smashing Pumpkins event. The enrichment items are hidden through out the animals' habitats or prepared and placed in a manner to stimulate natural behaviors. (Photo by Carlos Osorio/AP Photo)
