Rick takes Morty to another dimension to get some seeds for him but Morty's parents are considering to put Rick in a retirement home for keeping Morty away from school to help him in his lab.

It's around Christmas time and Jerry's parents are coming to visit so he wants everybody to have a normal holiday without technology and without Rick. Fortunately for him, Rick has other plans, involving building a molecular theme park inside of a friend of his named Ruben, and he shrinks down Morty and sends him in there to test it out.
