Ice Age: Collision Course

Peaches is engaged to marry a good-natured mammoth named Julian, to Manny's disapproval, as he finds Julian annoying and incapable of protecting Peaches. The concern escalates when Peaches reveals her wish to travel and explore the world as their honeymoon, which both Manny and Ellie oppose. Diego and Shira want to have children, but fear that they would not make any friends, as the other kids are afraid of saber-tooth tigers. Sid is about to propose marriage to his girlfriend, Francine, but is dumped by her and laments his solitude. During Manny and Ellie's wedding anniversary party, asteroids (caused by Scrat, who was propelled into outer space in an abandoned spaceship during an attempt to bury his acorn) strike the place and the herd barely escape. Meanwhile, at the underground lost world, Buck returns a Chasmosaurus egg back to its mother after it was stolen by a trio of flying dromaeosaurs named Gavin, Gertie and Roger. Buck discovers an ancient stone pillar and takes it to the surface, where he reunites with the herd.
