Muddy Fjord
泥まみれ渓流
Muddy Fjord is a Battle Cats stage in Cats Cradle Basin. It costs 210 energy and sends 18 enemy spawn lines — led by Corrupted Valkyrie as the boss — against a 1,050,000 HP enemy base, and clearing it rewards 506,331 XP. Its enemies carry the Alien, Black, Aku, Relic and Floating traits, so cats that target them do the most work here.
