Lineup: Manic Mohawk Cat, Manic Eraser Cat, Eraser Cat, Shigong Cat, Elemental Duelist Cat, Can Can Cat, Slime Cat, Cadaver BearCat, Bullet Train Cat, Awakened Bahamut Cat
This is by far the easiest stage in the subchapter, by a landslide. The Capies aren't threatening here, as they can be killed by E. Duelist and Can Can. For the zombies, just use Slime and Cadaver BearCat. If Miss Haka burrows too close to your base, use either Holy Blast, Bullet Train, or Awakened Bahamut. Sir Seal gets killed easily by Can Can as well.
