Tootsie Roll Pops
The quest Legend of the Star is a reference to a decades-old rumour regarding Tootsie Roll Pop wrappers that dates back to the 1930's. Some Tootsie Roll Pops come packaged in wrappers that depict a boy dressed like a "wild west Indian", shooting an arrow at a star. Ever since the wrappers were found rumours have circulated that there is some kind of secret prize attached to sending in wrappers. In the 1980's the Tootsie Roll company began replying to queries about the wrappers with a short story entitled "The Legend of the Indian Wrapper" that forms the basis for the story Festus tells the player upon the completion of Legend of the Star.

The terminal entries found in Sunset Sarsaparilla Headquarters depict the Sunset Sarsaparilla company capitalizing on a similar rumuor about star caps.
