Oswald The Lucky Rabbit is an antagonist in Five Nights at Treasure Island.
Oswald was never finished as said by Lisa in the second Night call: his suit is black, shorts appear to be somewhat melted, and no arms at all. He also makes an extremely loud scream when he jumpscares.
Like Photo Negative Mickey, Goofy, and The Face he is one of the suits that speak, he says things like.
"God, where are you God?"
- His voice is deep but his scream is extremely high pitched.
