Bionic Seaweed
ハイテク昆布漁
Bionic Seaweed is a Battle Cats stage in Quarantine Isles. It costs 120 energy and sends 14 enemy spawn lines — led by Metal Doge as the boss — against a 900,000 HP enemy base, and clearing it rewards 96,444 XP. Its enemies carry the Metal trait, so cats that target it do the most work here.
