Joy of 40 Million!
4000万人のハッピー！
Joy of 40 Million! is a Battle Cats stage in 40M Celebration Gifts Galore!. It costs 100 energy and sends 5 enemy spawn lines — led by DL Anniv. Doge Cake as the boss — against a 2,000 HP enemy base, and clearing it rewards 8,930 XP. Its enemies carry the Metal trait, so cats that target it do the most work here.
