Mocky, the little big-hearted male mouse, after being abandoned by his adoptive parents, tries to decipher the enigma to go in search of his real father and find his real family. His adoptive mother has given him only one piece of information: "Your real father fought with a snake to save you. The snake left a gash in the shape of a plus sign (+) on his right ear. I've been told he's known as "M and something with +". "M and something with +", that's not a name! We'll never find him", Alaki explains. We'll just have to ask for the mouse with the snake bite on his left ear, suggests Katana. Will Mocky solve the enigma that will allow him to go in search of his real father or will he give up?
