Cala Maria is one of the harder bosses. When she summons her ghosts, move up or down once they charge. Cala may fire a shock dolphin or a turtle firing cannons while a horse blows water trapping you from moving out of the way. Try to move forward when the horse comes out then move back when the horse comes towards you. Cala in the later parts will use her gaze to turn you to stone. Before she does move where there are no objects forward.
