Ominous Fin Alert
ふかひれ出没海域
Ominous Fin Alert is a Battle Cats stage in Cats of a Common Sea. It costs 220 energy and sends 9 enemy spawn lines — led by Trolly Blogger as the boss — against a 1,234,567 HP enemy base, and clearing it rewards 530,442 XP. Its enemies carry the Aku and Angel traits, so cats that target them do the most work here.
