Marlon is a male Mermaid Filly of Coralia. He is Coralia's youngest resident and spends his days working at the Underwater Petting Zoo, where he takes care of small animals, including but not limited to fish, seahorses and venerid clams. His tail fin is magical, and with it he can understand all of his zoo animals. In addition, he finds the female Mermaid Fillies to be pretty cute.
