|Occupation:||Coffee Shop Waitress|
|Voiced by:||Minty Lewis|
|First appearance:||"Brain Eraser"|
Eileen is a minor character on Regular Show. Eileen is a shy, intelligent, and timid mole. She works at The Coffee Shop with Margaret, better known as her co-worker and one of her really good friends, likely her best friend. She has a big crush on Rigby. Eileen first debuted in "Brain Eraser". She is voiced by Minty Lewis, who is also a storyboard artist for the show.
As said above, Eileen is a short mole with tan fur. Eileen looks surprisingly human. Her eyes are small and squinted. She has red glasses and wears the same uniform as Margaret. She has a small light brown tail and brown hair tied into a side ponytail. In Brain Eraser, her ponytail was on the right side, in Do Me a Solid, her ponytail was moved to the left side. In Brain Eraser, she didn't have white in her glasses, as seen down below, but in Do Me a Solid, she did.
When Eileen isn't working, she usually wears a pink shirt with ruffles around the neck and shoulders and a blue skirt. In "First Day," Eileen appears very different than usual.
She only had pupils for eyes like she did in "Brain Eraser" except her glasses were pointed down like reading glasses and she wore a purple shirt with a green oval in the middle with a small green skirt. Also, in "Camping Can Be Cool," she was wearing a light burgundy hoody and light army green shorts. Eileen never wears shoes in any episode just like Mordecai, Rigby, and Margaret. She and Margaret wear clothes, unlike Mordecai and Rigby.
Eileen is Margaret's best friend at the Coffee Shop, where both of them work. The two get along well, and are always seen together (whenever Eileen is present). Both share a friendship with Mordecai and Rigby, sometimes talking about them. Eileen also took care of her apartment in "Diary", but Mordecai and Rigby didn't know until Margaret told them about it. Although they usually get along, in Meteor Moves she is a bit annoyed when Eileen follows up Rigby and Mordecai's creative rap with an un-catchy factual rap.
Rigby has been Elieen's crush ever since "Do Me a Solid". At first Rigby didn't feel the same way and saw her as a pest. However, as the series progresses, it seems as though Rigby is getting used to hanging around Eileen. JG Quintel has noted this as an example of Rigby's growth as a character.
"Camping Can Be Cool" was probably the first time they had real relations. At first, after they lose the matches, Rigby and Mordecai argue for a bit then Eileen starts a fire the old fashion way. Rigby compliments her by saying "Yeah, that was kinda cool". Eileen blushes then Rigby, unsure of himself, creates a distraction by throwing the package of hot dogs at her. Then, later that night, they are seen playing video games on a log. When Eileen corrects Mordecai on the constellation, Rigby compliments her again, causing both of them to laugh. When they are running away from the Stag-Man, Eileen throws a rock in Margaret's car window, later when they are returning home Rigby admires Eileen by saying, "And you totally busted Margaret's window open with a rock".
In "Diary", while Rigby was revealing all of his secrets, he mentions that he thinks that "Eileen looks hot without her glasses on." It is found out the next day that Eileen was at Margaret's apartment, watering her plants, and heard him. She shows up to work without her glasses off (catching Rigby by surprise), but ultimately ends up running into a table.
In "In the House", when Rigby is turned into a house by the wizard, a picture of Eileen can be seen on the mantlepiece in the living room.
"One Pull Up" has a lot of interaction between Eileen and Rigby and possibly hints Rigby may like Eileen back. In this episode Eileen helps Rigby do a pull up and at the end of the episode Eileen and Rigby hug marking their first hug. Eileen also takes off her glasses again.
In "Meteor Moves", although he is much more tolerant of her annoying lectures on astronomy, he is really annoyed by her constant babbling, while he is trying to see if Mordecai will kiss Margaret.
In "Family BBQ", he and Eileen were seen playing cards together.
In "Tants", Rigby tells the Tants Co. founder that she worked really hard to make replica Tants, which made Eileen blush and they smile at each other.
Eileen seems to be good friends with Mordecai. Like in "Camping Can Be Cool" he invited her and Margaret to go camping and they both encourage Margaret that camping can be fun. Her, Mordecai, Rigby and Margaret usually hang out together. As well in "Death Bear" where he tackled Death Bear into a wall to save her. However, Mordecai was quite annoyed with her constant babbling about astronomy in Meteor Moves, as well as the fact that she was in between Margaret and Mordecai, when Mordecai was planning to kiss Margaret. He is irritated when Eileen follows up Rigby and his creative rap with an un-catchy factual rap.
Eileen has interacted with Muscle Man once in "Do Me a Solid" when Eileen, Margaret, and uninvited Muscle Man were having ice cream sandwiches at the house. In "One Pull Up," she said "Muscle Man was in here earlier", hinting that he comes to the coffee shop often. In "TGI Tuesday," Muscle Man says "hello ladies...and Eileen", and he helps her, Mordecai, and Rigby invite people to Margaret's surprise party at the "Parkside de Lux."
Tuck Packered was pretending to be Eileen's boyfriend to make Rigby jealous in "Cruisin'."
Both Eileen and Starla seem to be friends as seen in "The Longest Weekend" with how the two of them were shown to interact with one another, however how good of friends or how long they have know each other is unknown.
