Who manages fight all three of them and defeat them. Later, after Buck goes to the surface and finds his friends-The Herd. They listen to their conversation and hear that an enormous meteor is going to crash on Earth and kill all life. After they leave, Gavin and his children decide to sabotage their attempts stop the meteor. Concluding that due to their ability to fly, they will be able to survive, whilst the mammals won't. Afterwards, they track down The Herd and attempts to kill them. Thankfully, Buck manages to lead The Herd to the forest and once again defeat Gavin and his children. They try to repeat their attack later during a storm, but end up getting electrocuted. During nighttime, Gavin orders his son Roger to kidnap Buck, but he accidentally takes Granny, Sid the sloth's grandmother. Gavin tries to eat her, but fails and instead throws her off the ledge they were on, where she finds Geotopia. Finally, The Herd realize that the reason the meteor is coming is because of a magnetic attraction between the remains of the previous meteors that crashed on Earth, so they try to fill a volcano with the remains in order to blast it off to space and pull the meteor away. Gavin, Roger and Gertie intervene by grabbing and throwing the largest part off the mountain. Gavin then orders Roger to kill Buck. However, Roger realizes that they will not be able to survive the meteor's crashing. So he finally stands up to his father and manages to talk him into helping The Herd. Afterwards, they are last seen dancing to the ending song of the film.
