Nen Nen Korori

ねんねんころりこんころり

Nen Nen Korori is a Battle Cats stage in Mugen Train. It costs 60 energy and sends 8 enemy spawn lines — led by Enmu as the boss — against a 10,000 HP enemy base, and clearing it rewards 8,460 XP. Its enemies carry the Red trait, so cats that target it do the most work here.
