Brenham Backalive observes Marsu building a jaguar trap and of course uses his new knowledge to catch jaguars and earn a lot of money. He catches the mother of a little jaguar, who then lies alone and sad in the jungle. The little Marsus find him and drift all sorts of practical jokes with him, which Mama Marsu finally stops. They take the foundling home and after some friction, the four little ones become good friends. At night, the little jaguar hears his mother and makes his way to her.
