Here's where Manatsu and her friends met the Legendary Pretty Cure in a dreamlike state who gave them a new power called the Tropical Heart Dresser to defeat the new evolved monster called the Chou Zettai Yaraneeda, created by the Witch of Delays from her nightmares of the Legendary Pretty Cure which she was calling out for her. After receiving the Tropical Heart Dresser, the Cures manage to change into their Excellent-Tropical Style (which make them all barefooted) and perform their new group finishing move for the first time. This is from Episode 29.
