Zero Legends · Stage 2
Mermaid Lounge
マーメイド喫茶
Mermaid Lounge is a Battle Cats stage in Phantasmagoria. It costs 190 energy and sends 9 enemy spawn lines — led by Sir Metal Seal as the boss — against a 1,000,000 HP enemy base, and clearing it rewards 458,109 XP. Its enemies carry the Red, Alien, Zombie and Metal traits, so cats that target them do the most work here.
