Sign-up for Colorbox Mustard! (Music Coming Soon!) Use this Story: After the Rust Factory shut down due to the takeover of robots and machines, a new factory was opened. People of Mustard (especially Professor Mustard) had always wanted a factory to store all there bottles of mustard, but they couldn't due to the building of the Rust Factory. Luckily, they have one now, and even have a Mustard Bottle mascot named "Musty"!
