The Ruby Gloom franchise that led to the television show began as a stationery line, usually featured on pencil cases and backpacks, eventually expanded to clothing, keychains and plush toys. The character of Ruby Gloom is a small girl with bright red hair wearing a black dress with red-yellow socks. She is usually accompanied by her pet cat, Doom Kitty, and is described as "The Happiest Girl in the World." Originally Ruby Gloom was geared towards a gothic crowd but later was adapted for kids.
