Mucha Nu is a mixed creature with the body of a monkey but with scaley fish tail. He is one of the heroes in the epic tale of Ramayana. He's the son of the great monkey, Hanuman, and a giant's daugther, Suwanna Mucha. Although his mother is the daugther of the main villian giant, Tossakan, she has the uppr body of a beautiful woman and the lower body of fish like a mermaid.
 
The name "Mucha Nu" derrived from part of his mother's name , "Suwanna Mucha" which means fish and "HaNuMan", his father's name.
