Hangover
いくつになってもお年玉
Hangover is a Battle Cats stage in Happy New Year ?. It costs 110 energy and sends 13 enemy spawn lines — led by Lione Hippoe as the boss — against a 160,000 HP enemy base, and clearing it rewards 15,510 XP. Its enemies carry the Black trait, so cats that target it do the most work here.
