Yes! Precure 5 Movie: Kagami no Kuni no Miracle Daibouken!

Nozomi and her friends visit a castle-themed amusement park with Coco, Nuts, and Milk, expecting nothing more dangerous than costumes and attractions. Their fun ends when Coco and Nuts are kidnapped and carried into the mysterious Mirror Kingdom.

Guided by the twins Hidarin and Migirin, the five Pretty Cures enter a world ruled by Shadow, where they are confronted by dark doubles who look and fight exactly like them. To rescue their friends, each girl must overcome her own reflection before the enemy can use the kingdom’s power for himself.
