Lineup: Four Meatshields, Manic Macho Legs Cat, Drama Cats, Cyberpunk Cat, three big hitters like Bahamut, Ururun, Li'l Nyandam etc.
Items: Rich Cat
Cannon: Slow Beam
Spam Meatshields to slow down Dancer and Gato Amigo. Slowly summon Cyberpunk and the big hitters to slowly chip away at Dancer. Do not summon Macho Legs or Drama yet, they will be crushed by Dancer. When the other cats arrive, do summon them to get rid of the peons. The Slow Beam is rather useful here. When Dancer dies, just spam to win.
