The Ricks Must Be Crazy.Rick's flying car won't start, so he and Morty investigate the problem. The car's battery contains a miniature universe, from which Rick has been stealing electricity. Inside it, Zeep Xanflorp, that universe's top scientist, created a second miniature universe for the same purpose. Rick, Morty and Zeep are left stranded in a third miniature universe, as the pilot commits suicide and destroys his ship. Rick and Zeep constantly fight, and Morty abandons them and becomes a native chief. Morty forces the two scientists to work together to escape. Upon exiting the universe, Rick realizes Zeep wants to trap and kill him and Morty. While escaping, Rick reveals that Morty can turn into a car if needed. Ultimately, Rick and Morty leave the battery, trapping Zeep. Zeep is forced to discontinue his miniature universe research and have his people resume generating electricity to prevent Rick from destroying their universe. Meanwhile, Summer awaits in the flying car, where it uses violence to "keep Summer safe" from strangers, while she protests. However, it's effectively pardoned once it prepares a peace treaty, ending the human-spider war that has existed in this alternate reality. As a result, ice cream becomes served with flies to appeal to spiders.
