Flask Hill
フラスコ岳
Flask Hill is a Battle Cats stage in Laboratory Island. It costs 180 energy and sends 11 enemy spawn lines — led by B.B.Bunny as the boss — against a 850,000 HP enemy base, and clearing it rewards 289,332 XP. Its enemies carry the Red, Floating, Alien, Zombie and Angel traits, so cats that target them do the most work here.
