Special:Grandpa takes the Rugrats to a dual-screen drive-in (to the Rugrats, "parking lot movie"), so Grandpa can watch one film ("Deep Sea Divers of the Rugged North", a Testline production), while the Rugrats enjoy the title picture, Rosenmount Pictures' "Runaway Reptar" (directed by Jon Ho, whose name sounds like Hawaiian singer Don Ho), where Reptar was supposed to be saving the city from another large monster, a pterodactyl named Dactar. However, the Rugrats became disappointed when they find out that Reptar is actually helping Dactar in the destruction, rather than defeating Dactar. Through imagination (How else?), the Rugrats got into the film to help Reptar save the rest of the city from his "evil twin" and defeat another enemy -- Angelica, who invented Reptar's doppleganger, just so her parents can get her all the toys she want.
