After a long journey to return Roshan, a baby, to his tribe Manny, a mammoth, and Sid, a ground sloth found Roshan's tribe. His father, Runar, thought Manny was trying to hurt him, so the tribe's wolves barked and alerted the tribe. While the tribe was running toward them, Runar stopped them, for he realized that Manny was giving him his son. Runar was so happy he gifted the mammoth with this necklace, thanking him for returning his son. It's unknown if Manny still has the necklace and what's happened to it.
