Scooby and Shaggy befriend a penguin while working at a zoo. When they (as well as Velma, Daphne, & Fred) are invited to join him on a trip back to his home, Antarctica, they find that an ice ghost is haunting the way station there. He even has pushed the head scientist there into the ice. Velma is baffled by the increasing amount of suspects but eventually figures out who the villain is.
