She was most likely created to give the TV Series an important female character, since all the penguins and lemurs (and most of the other animals) are male. Marlene lives in the Asian Otter Habitat. She is friendly with the penguins, but she is mostly neutral and does not take sides between the penguins and the lemurs. Marlene is usually the first one the penguins go to when a five man team is needed. When a six man team is needed, she and Maurice are usually called. Marlene mostly visits the Penguin Habitat.
