Document 2: Dude, Where's My Car?: Thwarted, the five alien women merge to become a giantess who swallows Tommy alive. The giantess then crawls out of the amusement center and chases Jesse and Chester. The cultists tell them to activate the Photon Accelerator Annihilation Beam on the Transfunctioner. However, the button that activates it is too far in to reach. At the last second, Chester remembers the nature show with the tool - using chimps and uses a straw to push the recessed button, thus destroying the alien (Tommy survives, but Christie breaks up with him in favor of Nelson). The protectors thank Jesse, Chester and the twins for saving the world, and erase their minds concerning the events. The protectors park the duo's car, a Renault Le Car, behind a mail truck for them to find the following morning. Jesse and Chester salvage their relationships with the twins and discover the special treat from the girls turns out to be matching knitted caps and scarves. The protectors leave a gift for their girlfriends (and, for the two men): Breast Enhancement Necklaces. The film ends with Jesse, Chester, and the twins going in Jesse's car out for Chinese food while arguing what the tattoo said on each other's back.

They travel by train to the nearest station, but are once again confronted by Hinx; they engage in a fight throughout the train in which Mr Hinx is eventually thrown off the train by Bond with Swann's assistance.
