Color Charge!

Color Charge! (カラーチャージ！) is the official transformation phrase for Star☆Twinkle Pretty Cure. In order to activate the transformation, the Cures need their Star Color Pendant and their respective Star Color Pen.

Hikaru to Cure Star
Hikaru's pendant's top pops off, allowing Hikaru to insert her Star Color Pen. She shouts the phrase and draws a star in front of her to start the transformation. Pressing her pen against the pendant, Hikaru begins to sing and dance, drawing a circle around her as she goes to create her cuffs. She once again presses her pen to her pendant to draw a wave pattern which she skips in between to create her shoes. She then starts hopping from star to star, twirling the extra red wave to create her dress. She then proceeds to create her choker, earrings and have her hair grow longer and change its style. One last time, she presses her pen to her pendant to have it fuse with her dress before twirling the pen in the air and having it fly into its pouch. She stops singing and continues to introduce herself before striking a pose.

Lala to Cure Milky
Lala's pendant top pops up, allowing Lala to insert her Star Color Pen. She shouts the phrase and draws a heart that produces many smaller hearts and waves. Lala then rides the waves on a heart acting as a surfboard as she starts to sing. She touches the center of the pendant with the pen and draws several lines that become small hearts that create her cuffs and boots. She then touches the pendant again and draws a swirl that forms the top part of her outfit. She then dances around for a brief time while standing on top of a heart. After drawing some more, her shorts and her bow in the back are created. She then creates her choker, earrings, and her headband as her hair grows slightly longer and lighter, and stars with bright gold rings appear at the tips of her antennae. She then presses her pen to her pendant one last time as the cord disappears and it attaches to her dress. She then twirls around one last time as she draws the stocking on her left leg and the pen flies into its pouch. She stops singing and continues to introduce herself before striking a pose.

Trivia

 * This is the first transformation sequence where the girls must sing and dance in order to complete it.
 * In Cure Star's first transformation in episode 1, her sock appears twice; once when her shoes appear and once when her dress appears. This was corrected in episode 2, where her sock only appears when her dress appears.
