Cure Mermaid inserts her Dress Up Key into her Princess Perfume to transform into her Mode Elegant. She then crosses her arms and opens them, to rise a spinning circle of bubbles from water beneath her. She then shouts "Pretty Cure" and causes the bubbles to form one circle of water above her. She then says "Mermaid Ripple", raises her hands up to the circle and makes it turn into a swirl of water. The swirl is then shot upwards, towards the enemy. The water spins around the enemy, then closes in on the enemy and explodes into bubbles, purifying the enemy. After the enemy is purified, Cure Mermaid says "Gokigen'yō".
