Curly (Mouthwashing)

He is 40ish, all you need to know is that he was the captain of the Tuplar, Mouth washing (game). AND he is a bitch for not stopping Jimmy from crashing the ship and getting blamed for it while basically being a living crisp. He witnesses everyone get killed (and eats his leg) and then gets into the freeze pod that will most likely never get discovered.
"Curly (Mouthwashing) is my favorite character of mouthwashing"
NO HE IS NOT!!!! You clearly just feel bad he got burnt. He could've confronted Jimmy (Mouthwashing) about raping Anya (Mouthwashing)
