Fans generally praised Boo York, Boo York for: The "Garbage Boat" scene featuring the fish monsters
Creative Struggle: Pop star Catty Noir joins the trip hoping to rediscover her "musical voice," which she feels she has lost.
The climax reveals Seth as a descendant of a rival dynasty who wants to use the Heart’s power to restore his family’s lost kingdom. But the Heart can only be activated by a true heir—which turns out to be Catty Noir (her great-great-grandmother was the original keeper). With the power of friendship and song, the ghouls stop Seth from destroying the city, and Catty chooses to shatter the Heart rather than let it corrupt anyone.
"Steal the Show": A high-energy pop track that perfectly captures the "Main Character" energy of the ghouls.
