Thriller Grin
スリルの談笑
Thriller Grin is a Battle Cats stage in The Endless Wood. It costs 170 energy and sends 8 enemy spawn lines — led by Professor A. as the boss — against a 750,000 HP enemy base, and clearing it rewards 273,258 XP. Its enemies carry the Alien and Red traits, so cats that target them do the most work here.
