"Look at the Bright-side,
even in the Dark..."
- Ruby Gloom is a young girl who can find happiness in anything. "Look on the bright side" is her mantra. There isn't a single thing in the world that gets her down or a single negative that she can't turn into a positive. Her positive attitude has been shown to be helpful, as it allows Ruby to act as the voice of reason in the mansion, while her friends tend to lose focus on real issues. Ruby also has a crush on Skull Boy, who is one of her friends. One episode, "Sunny Daze", involves Ruby, Skull Boy, and Iris trapped in a cave looking for Misery. This caused Ruby to nearly reveal her feelings to Skull Boy. Also at the end of the episode "Happy Yam Ween", while having fun with paper, she kept on cutting Skull Boy holding hands with her and him alone. There have been several moments that confirm that Ruby has a crush on Skull Boy, such as in the episode "Quadro-Gloomia" when Frank and Len get inside Ruby's head and experience her feelings for Skull Boy first hand. Her positive outlook also makes Ruby very loyal to her friends and there's nothing she wouldn't do for any of them. She likes to have quiet time to write in her diary and knit.
- The Ruby Gloom franchise that led to the television show was created by the American company Mighty Fine Ruby Gloom began as a stationery line, and was featured on pencil cases, backpacks, clothing, keychains, and plush toys which were sold through doeworld a subsidy of Mighty Fine. Books were also made for the series, the first being Ruby Gloom's Keys to Happiness in 2004, as well as two calendars for 2004 and 2005. Ruby Gloom was depicted as a small girl with bright red hair, who wears a black dress and red and yellow striped socks. She has a pet cat named Doom Kitty, and was described as "The Happiest Girl in the World." Ruby was originally marketed to the goth subculture, but was later adapted for kids. The product line had an interactive website where users could chat in a forum, and click around for free things such as desktop icons and screensavers. The words: "Ruby Gloom is happy in her own way. Even though she is frowning, to her, a frown is only a smile upside down. In fact, Ruby is so happy, she could just die" greeted viewers as they entered the website. Towards the end of 2004 the website changed to forum only dubbed "The Mansion" By the end of 2004 the website had been redesigned and featured an interactive mansion to explore and user submitted artwork. Ruby is shown on the roof with her cat Doom and was given a smile for the first time. By 2006 "The Mansion" forum was removed, and the website had taken on its show format geared more towards kids.
