Four Season Heart Attack (フォーシーズンハートアタック Fō Shīzun Hāto Atakku) is the first group purification attack that the Season Heart! Cures use. To use it, the Cures need Bloom to produce the Flower, Sun, Wind and Snow Earth Crystals, which they have to insert in their Season Wands. This attack was first shown in Episode 16, and is capable of purifying a Hidoi, a person from the Dusk Area and a whole area around them.
Bloom shouts out a summoning incantation, which creates the four Earth Crystals. Cure Tulip flies towards the Flower Crystal and inserts the Crystal into her Flower Sceptre. Cure Flame flies towards the Sun Crystal and inserts the Crystal into her Sun Stick. Cure Maple flies towards the Wind Crystal and inserts the Crystal into her Wind Rod. Cure Snowflake flies towards the Snow Crystal and inserts the Crystal into her Snow Sword.
The Cures raise their Season Wands to the air, and the Crystals start to glow. Cure Tulip shouts her line, and the other Cures shout theirs. While saying 'Pretty Cure Four Season Heart Attack!', they draw a rainbow which flies straight at the enemy. They wave their Season Wands around to purify the enemy. The Cures then bow after the attack.
