Ellie is the mammoth that falls in love with the other mammoth that i do not know the name of
it is the mercy between the mother and the baby, also the mercy from the mammoth toward the baby.
In the original movie the mammoth's name was Manfred "Manny", the sloth's was Sid and the Saber tooth's was Diego. The baby went unnamed. In Ice Age: The Meltdown three new characters were added. They were a female mammoth named Elly and her two "brothers", Crash and Eddie. In the third movie, Ice Age: Dawn of the Dinosaurs Manny and Elly had a baby named Peaches, which was Manny and Elly's codeword for when Elly went into labor. Hope this helps.
