What the Waterway
どうなっとん堀
What the Waterway is a Battle Cats stage in New World Area: Ehen. It costs 150 energy and sends 12 enemy spawn lines — led by Elder Sloth as the boss — against a 1,200,000 HP enemy base, and clearing it rewards 361,665 XP. Its enemies carry the Black, Behemoth, Relic and Alien traits, so cats that target them do the most work here.
