Lime was a lime-colored Crewmate who wore a dark olive green bandana and brown, stained overalls with yellow buttons. Lime was an extremely cautious, paranoid, and secretive Crewmate who was always preparing for the worst-case scenario. As a conspiracy theorist, they distrusted easy explanations and often suspected that something strange was happening behind the scenes. Rather than spending time with the rest of the crew, Lime usually kept to themself, and could often be found lurking in vents or hidden corners of the ship due to a condition called "squish bone syndrome" which caused them to have a jelly-like structure and flexible bones. Lime is navigationally challenged, according to Orange, and their habit of gathering information and staying out of sight made them seem mysterious and sometimes a little suspicious.
