Pay Only Once! is a Battle Cats stage in The Battle Cats POP!. It costs 60 energy and sends 9 enemy spawn lines — led by St. Pigge the 2nd as the boss — against a 160,000 HP enemy base, and clearing it rewards 11,280 XP. Its enemies carry the Red trait, so cats that target it do the most work here.
