8 Years of Fun!

祝！８周年！！

8 Years of Fun! is a Battle Cats stage in B-Day Gifts. It costs 8 energy and sends 5 enemy spawn lines — led by 8th Anniversary Birthday Cake as the boss — against a 1,000 HP enemy base, and clearing it rewards 413 XP. Its enemies carry the Metal trait, so cats that target it do the most work here.
