Doki Doki! Pretty Cure Episode 17

Possessed from an unassuming red diamond she just picked up, Regina suddenly becomes overwhelmed with anger and turns against the Pretty Cures, summoning a sculpter-like hammer Jikochuu to fight them. Said monster has the ability to fire dark eye lasers that turn anyone to stone on hit, which it uses to petrify Kenzaki Makoto, Yotsuba Alice, and Hishikawa Rikka. They're all eventually restored back to normal by Aida Mana's Heart Shoot attack.
