Fan Casting Sailor Shrimp in "Shenanigan Shanty" in IDEAS FOR CUPHEAD BOSS BATTLES

You're on a fishing boat and you fight on the decks with a shrimp who are sailors. They go shrimping (not to eat them, to expand their army). They'll spew bubbles at you (some are pink to parry), and haul up the fishing net and smaller shrimp fall down on you from the bottom of the net (some are also pink to parry). In the final phase, all the shrimp bunch together and transform into a gigantic version of the admiral.
