In Ice Age: Continental Drift, he gets into an argument with his teenage daughter before being pulled away in by the drift with Diego, Sid and Granny.
He and the team later encounter a group of pirates led by Captain Gutt. A running gag for Manny, shown in four of the five films, is that if a certain character were to refer to him as fat, he would often deny it, saying that "his fur is what makes him look big" and that "it's poofy".
In the third film, he adopts a trio of baby T-Rexes, and is forcibly taken to the underground dinosaur land by their mother, requiring the others to come and save him.
In the fourth film, it is revealed that his full name is Sidney, though this name was also used in a deleted scene of the first film.
When Manny had saved Ellie from drowning, they helped Ellie back onto solid ground, but almost drowned when the flood was encroaching.
Eventually however, the waters drained, leaving Crash, Eddie, and all of the others alive.
They first made their presence known to the opening characters by means of shooting pebbles through reeds at Sid and Diego, then roasting them so as to humiliate them, but Diego began chasing them, leading both Sid and Diego to Ellie.When he, Diego and Manny are on the ice and are forced up by a water spout, they see a rainbow in the bright blue sky as he told them that "there is a rainbow at the end of every corner." A mechanical version of Sid appears in Robots during the miming scene.Sid was built along the form typical of ground sloths, short, brushy tail, clawed hands and feet, a long thin neck, ovular head with bulbous eye on both sides and a pair of buckteeth.Crash and Eddie joined Ellie in trying to escape the flood, but soon ran into trouble when they were trapped in a cave.Ellie insisted that they leave her to the point of pushing them outwards from a small crevice, but they promised to return with help, and true to their word, persuaded Manny to try and free Ellie.
