Movie plot
In Transformers: Dark of the Moon, Wheelie and Brains are kept as 'pets' by Sam Witwicky. Brains is more perverted than Wheelie, and likes bothering Carly. He also does not like it when Sam and Carly treat them as pets, wishing merely to find a place to call home. Wheelie and Brains are later taken by Carly and Sam to see Lennox after Sam was attacked by Laserbeak at his work place. He helps Sam and Simmons find two former cosmonauts who are hiding in America. During the battle in Chicago, he rides with the Wreckers and cheers as they ride into battle. He and Wheelie are accidentally left behind, but find a crashed Decepticon fighter and fly it to the main Decepticon battle-cruiser, where they sabotage the ship, saving Bumblebee and the other captured Autobots. They then crash the ship in the river. Before the ship crashes, Wheelie has a brief exchange with Brains in which Wheelie says that "we had a good run Brains" who responds, "yep, we're gonna die". The ship crashes into the river and the whereabouts of the two are unknown for the rest of the movie.
