Rapunzel's Tangled Adventure, Season 3

Eugene:
(narrating) This is the story of two best friends. Okay, so they don't look like best friends at the moment. It's, it's complicated. You see, her whole life, Cassandra has felt second best. Going back to when her own mother, Gothel, chose Rapunzel over her. And as a result, Cass has developed, a, uh, a grudge. That little thing there, that's the Moon Stone, and it's the cosmic counterpart to, a-ha you guessed it, to the Sun Drop. The two belong together, but that's not the way Cass sees it. To her, the Moon Stone is her destiny. And now that she has it, she's out to take down Rapunzel, Corona, and anyone, who underestimated ever her.

Cassandra:
You have to be careful who you trust.

Eugene:
(continues narrating) Not only does Cass have a brainwashed Brotherhood on her side, she also pals with this goat-headed monster. (Milton the Goat bleats then Shorty is shown) No, no, not that one. This one. Zhan Tiri, an ancient, evil demon. Only now, old Zhan Tiri looks like this. Zhan Tiri manipulated this fight between Cass and Rapunzel to gain the power of both the Sundrop and Moonstone. It's enough to make the most resilient hero give up. But good thing this is Rapunzel, we're talking about.
