For anyone finding this story who's unfamliar with the orginal show, The show revolves around the adventures of the members of the Smith household, which consists of parents Jerry and Beth, their children Summer and Morty, and Beth's father, Rick Sanchez, who lives with them as a guest. According to series creator Justin Roiland, the family lives outside of Seattle, Washington.
Rick is an eccentric and alcoholic mad scientist who has successfully created portals to other universes and dimentions, often becomes a key part of the show and humour. He's also exteremely cynical, condesending and vile, but is actually a good person underneath. As the title suggests he constantly brings his grandson Morty along, often against Morty's wises. Other times it's other members of the family, most often Summer, who's 17 while Morty's 14. Beth doesn't like that Rick constantly endangers Morty, but she's she's too much of a doormat to stand up to him, at least at first, being too scared he's gonna leave her like when she was kid. Jerry, despite being a dimwit has enough common sense to do so though, and the two are other at odds with each other. Plus Jerry is a buttmonkey in general, him also being a doormat. Even more than Beth.
Not spoken in the show, but in this story it's somewhat impied he's involved in most other existing cartoons, much like Villainous.
The story starts off recaping THE RICKS MUST BE CRAZY where Rick, Morty and Summer discover that Ricks car won't start because its battery is malfunctioning. Rick takes Morty inside the car battery to repair it and leaves Summer waiting in the car after giving it the instruction "Keep Summer safe." so his grandaughter won't be in any harm during Rick's absence.
Morty discovers that the car battery is actually a 'microverse battery', containing an entire universe to supply power to the car, Rick telling them "the bird" is a symbol for peace, and that ''fuck you'' means ''much obliged'', and ''blow me'' means ''thank you''.
Rick and Morty discover that a scientist and microverse citizen named Zeep Xanflorp has made his own 'miniverse', which renders gooble boxes obsolete. Rick, Morty and Zeep enter the miniverse, and discover that Kyle, a scientist living in Zeep's battery, is also working on his own 'teenyverse', which Morty and the three scientists enter. Once both Zeep and Kyle discover that they are slaves born to make electricity, Zeep attacks Rick in a rage. During the struggle, Kyle commits suicide using his spaceship, leaving Rick, Morty, and Zeep stranded in the teenyverse.
Several months later (in teenyverse time), Rick and Zeep put aside their differences and create a way to get back to Zeep's world. When they get back however, Zeep attempts to kill Rick and Morty, and after a brawl, Rick ultimately defeats him. Rick and Morty safely return to their universe, while Zeep realises he must stop his experimentation with miniverse technology and return to gooble boxes, or else Rick will throw away the battery and destroy his world. He does flip off Rick though, this time in the correct context, going by the fact he did the same joke to his own microverse, he now realizes it's true meaning.
Meanwhile, Rick's car uses extreme defensive tactics, including dicing up a person, paralysation and psychological torture, all to keep Summer safe from various assailants. Summer, clearly tramatized, attempts to stop the car from hurting anyone, an escalating standoff ensues between the parked car and the police and military. Upon Summer's continued demand, the car forgoes physical and psychological violence and instead escapes the situation by somehow creating a peace treaty between the humans of this timeline, and a spieces of giant spiders, that were using mind control to walk the humans into webbings to eat them later.
Rick, Morty and Summer go to a ice cream shop on the same planet. But Rick complains about flies that are in his ice cream, which the waitress tells him ice cream is now for both humans and spiders. Rick gets mad at Summer, who blames Rick's ship, but Rick says "don't blame my ship Summer!"
During the argument, if you listen to Rick, he somehow blames this on Summer's boobs, saying they ruined ice cream.
Despite all this, it later turns out Rick was keeping in contact with the spiders and made them his allies, which becomes a plot point later on, least for this particalar story. And appearently they can speak english. Or he found a way to teach them it. He also also pulls the same stunt about 'the bird' meaning peace amongst worlds, and that they have to give him backrubs, or their babies will be born mentally disabled. Most of them are smarter than that, but still give him one anyway.
