Eileen

Eileen Roberts is a major character in Regular Show. She was originally a waitress at The Coffee Shop and a student at the City College. During that time, she had a crush on Rigby. While turned off by her at first, Rigby does eventually begin to like her and become friends with her. They begin dating a few months before "Dumped at the Altar" and got married. After marriage, they had two children, whose names are unknown. She is voiced by storyboard artist, Minty Lewis.

Personality
Eileen is a shy, intelligent, and timid mole girl.[2] Minty Lewis describes Eileen's first appearances as coming off "as a pretty big weirdo nerd with major hots for Rigby". However, her character began to develop more in "Camping Can Be Cool", as she is shown to be resourceful when he, Mordecai, Rigby, and Margaret went camping, knowing how to start a fire after they forget the matches, impressing Rigby, along with knowing the name of a constellation Mordecai and Margaret were looking at without even looking up from the video game that she and Rigby were playing. Minty Lewis thinks that viewers have come to see her weirdo neediness "as more charming than off-putting". She can be dorky at times, as she has a rock polisher, and intelligent, as she has shown to get straight As in her college classes. Up until the end of "Snow Tubing", Eileen had a phobia of snow tubing due to getting hurt in a snow tubing accident when she was little. As seen in "I See Turtles", "Crazy Fake Plan", and "Do Me a Solid", it is revealed that she loves sea turtles.

Appearance
Eileen is a 3'6" mole girl in her early 20s with tan fur. However, her appearance is very humanoid, excluding her toes and tail.

She wears red round glasses and has two eyelashes on each of her eyes. Without her glasses, her eyes are just two black dots with eyelashes. She has a small, oval shaped light brown tail, and shoulder length brown hair with some of it tied into a side ponytail. During her debut in "Brain Eraser," her ponytail was on the right side her glasses did not have white in them, and they were narrowed down, showing her pupils. She has noticeable front teeth, and they occasionally stick out of her mouth like buck teeth. She has an unhealed scar on her lower middle elbow due to a snow tubing accident when she was a child. She has two toes on each foot, and is usually barefoot, although around Season 5 she began to wear shoes more often, which most often are red flats.

She wears the same uniform as Margaret at her job at the Coffee Shop; a short sleeved tan top with a light blue collar and cuffs and a tan skirt.

Her most common outfit outside of work, especially in Season 8, is a pink t-shirt and blue jeans with the cuffs rolled up.

In Do Me a Solid, her attire outside of work was a pink shirt with puffy sleeves and ruffles around the neck, and a blue skirt. This outfit is seen again in "Cruisin'" and "One Pull Up".

In later episodes, in Seasons 3 and 4, she started to wear sweatshirts, one of which is a light burgundy color, which was worn with green shorts, as seen in "Camping Can Be Cool". Another sweatshirt she wore was light purple, and she usually wore blue jeans or a blue denim skirt with it, first seen in "TGI Tuesday". In Tants, she wore a pink sweatshirt with a light blue skirt.

Another outfit she is seen wearing is either a pink or light blue shirt with a white collar and a blue skirt.

In "Dumped at the Altar", she wore a pink dress, with a light pink top and a darker pink skirt with light pink flowers on it, to Muscle Man and Starla's wedding. Her hair was up in a bun and had small curls of hair over her ears.

In "Rigby Goes to Prom", she wore a sea foam green dress, with a teal bow around the waist, a poofy skirt with a frilly white layer underneath, teal shoes, and white gloves to Rigby's prom. Her hair was in an up-do with a bun on top.

At the 25 year park reunion, an older Eileen has slightly longer hair that is worn down under a dark red beret, and she is wearing a pink sweater with a mauve skirt. She also has bags under her eyes. During the time montage, she wears a short pink dress with a purple belt, her ponytail is on top of her head and her bangs are in a messier fashion, and she still has bags under her eyes.
