Fiber Cookie
サーターアンダギー
Fiber Cookie is a Battle Cats stage in To the Future. It costs 110 energy and sends 8 enemy spawn lines — led by Teacher Bun Bun as the boss — against a 160,000 HP enemy base, and clearing it rewards 15,510 XP. Its enemies carry the Red and Floating traits, so cats that target them do the most work here.
