Character: fish funky

Fish Funky is a character that features in the arcade game The First Funky Fighter.
She appears in groups and they act just like regular enemies, but instead of attacking the player they dance on the screen until you punch them, when punched, the top of her swimsuit gets torn off, this gives the player a 100 points for each one they punch, when the regular enemies of the game give 40/50 when hit.

In swamp stages (1 and 3), theres also an alligator lady that works the same way.
