Episode Summary

The episode starts with Ben, Gwen, and Kevin trying to enjoy a rare day off at the beach. Their relaxation is cut short by a sudden attack from a massive, mystical Rock Monster. Ben transforms into Goop to fight it off, but the creature is mysteriously pulled back through a portal before they can investigate. Unbeknownst to them, the entire event was orchestrated by Gwen's old rival, Charmcaster, who is observing them from a hidden lair.

Frustrated by his hideous mutation and an accidental argument with Gwen, Kevin leaves the group to fix his holographic ID mask. Charmcaster seizes the opportunity, transforming her appearance into an attractive human teenager named "Caroline." She intercepts Kevin, fakes an accident, and pretends to be entirely fascinated by his true, mutated form. Blinded by her affection, Kevin is easily put under a literal hypnotic love spell, falling entirely under her command.

Under Charmcaster's manipulation, a brainwashed Kevin betrays the group, luring Gwen directly into a magical trap at a mystical planetarium. Charmcaster's true goal is revealed: she intends to drain Gwen's vast, innate Anodite mana energy to exponentially amplify her own sorcery. Ben rushes to the scene, facing off against legions of rock creatures, while Gwen must find a way to snap Kevin out of his trance and defeat her magical counterpart before her life force is stolen completely.
