Neil deBuck Weasel was a space astronomer expert who existed as a figment of Buck’s imagination and helps the herd as they attempt to stop an asteroid from destroying the planet[1]. The science maven and matter explainer insides Bucks head knows everything about the cosmos and the looming Scrat-astrophe.


Neil deBuck Weasel started off as the narrator of the start of the film, explaining what and how the universe was created. Neil deBuck Weasel and his friends, Pythagorus Buck and Robo Buck were characters in Buck's mind that helped Crash and Eddie understand how the space rocks would help them save the world. A few days later, when Buck was captured by a a group of dino-birds, once they revealed their plan on surviving the asteroid, in Buck's head, Neil deBuck Weasel admitted that the plan had majored flaws and it was the stupidest thing he's ever heard. After the asteroid was diverted, Buck ended up at Julian and Peaches's wedding, dancing, as his figments danced as well. Neil later teaches the audience about the planet Mars.
