|Rocko's Modern Life character|
|Voiced by||Carlos Alazraqui|
|Species||Wallaby (described as "Brush Wallaby" in concept sketch)|
Rocko is the eponymous fictional character of the cartoon Rocko's Modern Life and the comic book series of the same name. Rocko was born in Australia and emigrated to America in High School. He was pitched to Nickelodeon executives as having the personality of a young wallaby Woody Allen. Carlos Alazraqui provided the voice of Rocko in the television series.
Conception and development
Rocko first appeared in a never-released comic, where he has the name "Travis". Joe Murray, creator of Rocko's Modern Life, believed that the personality of a wallaby suited Rocko after observing a zoo wallaby "minding his own business" while elephants and monkeys "screamed for attention."  After the event, Murray said that "[i]t kind of clicked. Rocko would be at the center of the hurricane of everything swirling around him. He'd be like the everyman who's affected by the dramatic personalities around him."
Murray wanted to get his comic into syndication. Afterwards Murray made substantial changes to Rocko. Murray added that the personality of a wallaby mirrored Rocko's humbleness and his tendency to keep his frustrations to himself instead of publicly complaining about them.
In the original pilot for Rocko's Modern Life, the animators colored Rocko yellow. One month before the first episode was submitted to the animation studio in South Korea, Murray changed the color when a toy company wishing to make Rocko plushes refused to license the character after citing that Rocko looked too similar to a yellow character used in one of the company's existing products. Murray fought the changes with the Nickelodeon executives; in the end the executives insisted on changing the color, so Murray changed the color to beige and disliked the choice. On his website Murray said, "He was always yellow to me."  Murray said that the company later backed out of the commitment and did not create the plush series.
Murray auditioned Alazraqui in San Francisco, and chose him as the voice actor for Rocko. Jeff "Swampy" Marsh, a storyboard writer, describes Alazraqui's voice for Rocko as "not really an accurate Australian accent" [sic]; according to Marsh the team used the voice as Alazraqui used the voice for the pilot.
Murray said that as the series progressed, he adjusted Rocko's design from episode to episode to be more "volume friendly" and "animator friendly." According to Murray, when he created independent films and the Rocko's Modern Life pilot, he created all of the character layouts in his mind and other animators used the layouts to create works. Murray said that when Rocko became "high volume," Murray taught Americans and Koreans how to draw the characters. Murray described Rocko as the most difficult character to draw, and he said that therefore he decided to adjust his character design in order to assist the overseas animators. Murray said that as he and the directors continued to "quickdraw" the character changes to the design "naturally" lessened the "victim, paranoid" aspect and gave the character a "happy personality."
According to George Maestri, Rocko has no family name because the writers did not think of a family name that they desired. In a concept sketch Murray named the character "Rocko Rama". The writers considered the family name "Stretchbrain" because the character's brain popped out of his head during "odd moments."  The writers scrapped the idea, leaving the character with one given name. Some websites, including Hot Topic, give him the family name "Wallabee" and the middle name "James". In "Dental Hyjinks," the first story of the Marvel Comics Rocko's Modern Life series Issue #1 , the nurse addresses Rocko as "Mr. Rocko." In "Intestinal Turmoil," the first story of Issue #2, the doctor addresses Rocko as "Mr. Rocko" and Rocko answers the telephone with the words "Rocko residence."
Change in model sheets
Rocko's design changed as his character evolved. The first version of the character was Travis. Murray said "I liked him, but changed him considerably for Rocko." Murray said that the version placed in the Rocko's Modern Life proposal was "much looser, and closer to my independent film style." Murray did not consider how the character would be animated, as Murray did not believe that the character would be animated. When the pilot for Rocko's Modern Life was approved, Murray began streamlining the character so that others could easily draw him. Murray said that one could perceive a difference between the character as he appears in the original model sheet used in the original animation versus the character as he appears in the animation produced abroad. Murray continued to streamline Rocko so that overseas studios could easily draw him. Murray and the directors had become so accustomed to quickdrawing Rocko that the changes in the character, in his words, "naturally occurred, lending more to the happy personality Rocko had developed into ( less the victim, paranoid one from the beginning)."
Rocko lives in O-Town, California. Raised in Australia, Rocko later emigrated to the United States after he graduated high school. Murray suggests that Rocko's interest in the United States began with a vacation with his family as a youth; during the trip he met his future sidekick Filburt. Murray allowed for directors to create inconsistencies, reflecting how friends possess different and varied, nostalgic memories of the past. For instance, in the episode "Put to Pasture" the writers portray Rocko, Filburt, and Heffer Wolfe as students at O-Town High School. Murray received many pieces of mail regarding the storyline inconsistencies.
Rocko wears a blue shirt with purple triangles and orange shoes. He is known for being a loyal friend, not venturing outside his comfort zone, and is known to say when a situation is not going well: "_____ day is a very dangerous day." (For example, "Garbage day is a very dangerous day.") In "Trash-O-Madness", a family photograph depicts Rocko with a mother, father, and a younger sibling. "Wimp On the Barby" shows Rocko's family again, revealing that his younger sibling is a sister. Murray created a narcoleptic older sister character named Magdalane "Maggie" and an episode, "Wake Up Maggie", about her, but chose to never air the episode and never use the character. Magdalane was created as a mother with two children.
Although personally hygienic, Rocko has an almost pathological tendency to neglect his living space; several episodes, such as "Unbalanced Load", involve Rocko attempting to rectify severe messes or lapses in maintenance.
Rocko enjoys collecting comic books and likes rainbows.
Nickelodeon South East Asia's website describes Rocko as "generally very polite and sometimes shy" and that provocation can lead Rocko to become "determined and forceful." Jean Prescott of The Sun Herald described Rocko as a "pudgy little wallaby star" who tries to "do what's right" and is devoted to his friend Heffer and dog Spunky. Prescott has called the character "lovable."
Common Sense Media reviewer Andrea Graham, whose review is posted on Go.com, describes Rocko as "paranoid and obsessed with cleanliness" and that he initially perceives his neighbors to be "loud and messy." Graham describes Rocko as accepting of his neighbors' faults and seeing the positive qualities within them.
In the television show, in his day-to-day life, Rocko works as a cashier at (and briefly as the boss of) a local comic book shop called Kind of a Lot o' Comics which is owned by Mr. Smitty and sells mostly Really Really Big Man comics. Rocko originally worked at Mega Lot-O Comics, owned by chairman of Conglom-O, Mr. Dupette, Ed Bighead's boss. In the television show, his other jobs include tattoo artist, plumber's assistant, and specialty phone operator (possibly a phone sex operator, as he says "oh baby, oh baby, oh baby", and the sign behind him says "Be Hot, Be NAUGHTY, Be Courteous."), a product tester at Conglom-O, a tow truck man, an underwear model, and a cartoonist for the program Wacky Delly.
In the official comic book, Rocko works as a comic book dealer in Issue #7's "Conned Again", working for "Humongo Con."
Rocko's neighbors are Ed, with whom he has a semi-rivalry, and Bev Bighead. Bev considers Rocko a very sweet neighbor. He and his dog Spunky, who often eats the neighbors' salmon bushes, are a source of constant annoyance to Ed. In the episode Skid Marks, Rocko's drivers license reveals that Rocko and the Bigheads live on "Boogie Blvd," with Rocko's address being 1172 Boogie Blvd.
Rocko's best friends are Heffer Wolfe, a bull who eats a lot and was adopted and raised by a family of wolves, and Filburt, a bespectacled turtle with neurotic Woody Allen-esque mannerisms, who often feels nauseated.
In early concept sketches Murray indicated that Rocko bears a strong crush on a character named "Melba Toast". Rocko expresses this trait in Season One, bearing a crush on the unseen character until he discovers that Melba has a serious boyfriend named Dave in "Love Spanked". Melba has only been mentioned once since.
In subsequent episodes, Rocko bears crushes for other characters. In "S.W.A.K.", Rocko has been vying for the attention from the pretty kangaroo mail-lady that comes to his door every day; he writes her a love note that he is too scared to send so Heffer does it for him instead. Rocko fails to retrieve the letter and gets the impression that the mail-lady would rather go out with Heffer. This turns out to be a joke on the mail-lady's part and she actually returns Rocko's feelings. In "Wallaby on Wheels", Rocko learns to roller skate to impress Sheila, a girl who hangs out at the roller rink, and becomes jealous when it is implied she is attracted to Heffer. In the end, he wins her over after saving Heffer's life. In "I See London, I See France", Rocko tries to win over Claudette, who turned out to be his female wallaby pen pal from Paris, but she is more interested in Heffer.
