The least understood of the crew, often mistaken for Dr. Toxic until they recognize her hat. Holiday always seems jolly and relaxed. All but Dr. Toxic trust Holiday as far as he can smell cheese from a store window. She is fairly lazy but usually does her tasks after a crisis.
As a Crewmate, Holiday does tasks whenever she feels like it. Nobody but Dr. Snowball and Dr. Toxic question it between themselves.
As an Impostor, Holiday appears at perhaps the weirdest moments that even Dr. Toxic would cal "Strange and Unusual".
