1x20 - Star☆Twinkle Precure

The Cures catch up to Blue Cat as she reveals her true form as a transforming cat alien, revealing how she learned that the Star Color Princesses' power combined with Fuwa would unleash a great power that she wished to use to restore her people. Just then, however, the group finds themselves attacked by a vengeful Eyeone after she turns herself into a Notrigger. Seeing the Cures risking their own lives to protect her even after everything she had done, Blue Cat's desire to save them causes her to gain the power to become Cure Cosmo.
