After Fish was banished from the mob by Carmine Falcone for her betrayal of him, Falcone gave the business to her former umbrella boy Oswald Cobblepot (who exposed her traitory) and got him to do it up and remove any reminds of Fish. The club was renamed Oswald's and the fish logo was replaced with a neon umbrella sign. When the club began to fail, Falcone got a brainwashed Butch to help with the running due to his experience.
