Underground B55F is a Battle Cats stage in Underground Labyrinth: The Grand Deep. It costs 40 energy and sends 7 enemy spawn lines — led by Spacefish Jones as the boss — against a 800,000 HP enemy base, and clearing it rewards 2,256 XP. Its enemies carry the Angel, Alien and Floating traits, so cats that target them do the most work here.
