A Strange Bottled Girl
謎のびん詰め美少女
A Strange Bottled Girl is a Battle Cats stage in Merc Storia: Showdown. It costs 85 energy and sends 9 enemy spawn lines — led by Aura (Enemy) as the boss — against a 80,000 HP enemy base, and clearing it rewards 11,985 XP. Its enemies carry the Floating trait, so cats that target it do the most work here.
