The Mermaid Boss who appears in Cuphead was most likely inspired by Betty Boop. When she blow’s her face resembles Betty’s which indicates this is 100% true. Later this year the game will be coming to Xbox One and PC. When it comes to PC i’ll be getting it. As it is very much so inspired by retro 1930′s cartoons, also the Fleischer Studios come to mind.Very unique as no other gaming company as thought of this style as of yet.
