Spiral Heart Splash Star (スパイラル ハート スプラッシュ スター Supairaru Hāto Supurasshu Sutā?) is the group attack used by Cure Bloom, Cure Egret, Kiryuu Michiru, and Kiryuu Kaoru during the final battle against Goyan. The name of the attack's last part is the same as the title of the show, Splash Star.
Moop, Foop, Flappy, and Choppy tap into their powers, giving Cure Bloom and Cure Egret the Spiral Rings, and making the symbols on Michiru and Kaoru's uniforms glow. One by one, the girls recite their parts of the incantation as blue, yellow, pink, and green energy comes into their hands. The blue and yellow energy becomes liquid and forms a heart. Cure Bloom and Cure Egret get ready to push the liquid back, as do Michiru and Kaoru. At the yell of "Splash Star," all four release their liquid in a devastating torrent that destroys the enemy in a ball of white light.

- This attack is very similar to Extreme Luminario Max which also appeared at the end of the last season as a one time finisher attack, with Goyan being destroyed by an ultimate attack just like Baldez was.
