Mustard is a female contestant in Object Land.
Personality
Prior to Object Land Reloaded episode 2, Mustard seemed to be a standard 'valley-girl' stereotype alongside Ketchup, who was her inseparable friend. They were Lollipop's fans, in spite of her rude nature. In episode 2 of Object Land Reloaded, it is revealed that Mustard is an android created by Ketchup, drifting away from the original valley-girl stereotype.
