HappinessCharge Precure! Ningyou no Kuni no Ballerina

A performance is about to begin when the dolls suddenly speak, asking for help. A ballerina named Tsumugi directs the Pretty Cures to the Doll Kingdom. Expecting a land of cute stuffed animals, they instead encounter Black Fang, a mysterious figure attacking the kingdom and capturing Tsumugi. The once joyful realm now hides sorrow, and the Pretty Cures must act to restore it.
