Sue Ellen Moves In

Sue Ellen Moves In is the first half of the 21st episode of Season 1. It first aired on February 10, 1997 with The Perfect Brother.

Summary
Rumors are circulating about the new family that has moved in and Buster thinks that they may be aliens, even after he's met Sue Ellen. When Buster's mom invites Sue Ellen's over for dinner, he finds out that Sue Ellen isn't an alien, but just a kid who has lived in various places around the world.

Plot
Arthur tells of the times in which he and his friends have made friends with other people. He recalls how Muffy and Prunella used to hate each other when they first met, but were eventually able to settle their differences and become best friends. He then recalls how Binky used to pick on the Brain, but they have since learned to tolerate each other. He then recalls when they all met Sue Ellen.

After the title card, Arthur, Francine, and Buster are sledding in the snow, until Buster spots a moving van at a nearby empty house. When they see a bike, they realize that the new family has a kid. After the movers leave, Francine goes home for lunch while Buster and Arthur take a close look. The house is pitch black until the lights turn on by themselves! Terrified, they run away and hide. Buster immediately suspects that this new family is not normal.

The two boys decide to investigate further, and create a homemade periscope to spy on the house. There, Arthur spots a girl unraveling new furniture and props. Buster looks for himself and is horrified by what he sees, as none of the furniture looks familiar to him. He suspects that the new family must be aliens. At the Sugar Bowl, the gang discusses the strange occurrences at the house. Francine suggests the lights were on a timer, but Buster is convinced that they are aliens. Prunella tells them that she heard a rumor that the family's been all over the world, and suggests they were cat burglars who robbed the Lourve in Paris, France. They then fled to Elwood City to stay undercover. Arthur rejects this, instead suggesting she's a superspy who's on the run for stealing valuable secrets from other nations. Buster says that's ridiculous, and says that they are aliens disguised as humans to prepare for an invasion. The gang is dumbstruck at this idea. Soon, rumors are flying over the new kid, with everyone making up a different story about her. At one point, the whole gang is on the phone, but they don't understand each other due to the overlapping messages. Binky gets off and accidentally calls Mr. Ratburn, but quickly hangs up.

One day, Arthur and Buster are playing in the snow when they finally meet the new girl, Sue Ellen Armstrong. They are scared around her but manage to talk to her. Sue Ellen is astounded by the snow, remarking that she's never seen it before, much to the boys' astonishment. Later at night, Buster, Francine, and Arthur come across Sue Ellen's house, and hear strange music, which Buster thinks is outer space music. They panic and run, with Buster rushing home. His mom tells him that the new family is coming for dinner, much to his horror. He locks himself in his room, thinking that the new family is on to his suspicion that they are "aliens". Arthur shows up later to reveal that Buster's mom interviewed the family for the newspaper. As it turns out, Sue Ellen's family has lived all around the world, which explains their strange lifestyle. Buster is still nervous however, so he invites Arthur to dinner so he can eat normally with Sue Ellen. The night goes well and Arthur suggests that Sue Ellen introduce some of her unique stuff to her new class, as they might find it interesting.

Sue Ellen becomes a student in Arthur's class and tells them about her life around the world. Her father is a diplomat so they moved a lot. He last worked in Costa Rica, which had no snow. Buster is still suspicious though. Sue Ellen then invites Buster and his mom over for hot dogs, and Buster, unable to control himself, eagerly accepts. He finally accepts Sue Ellen as a friend, remarking that Sue Ellen and her family must be "friendly aliens".
