Sleepless Children
寝ない子供
Sleepless Children is a Battle Cats stage in Night 1: Santa Claws at Work. It costs 50 energy and sends 12 enemy spawn lines — led by Christmas D. as the boss — against a 30,000 HP enemy base, and clearing it rewards 7,050 XP. Its enemies carry the Floating and Red traits, so cats that target them do the most work here.
