Sea Urchin Cave
ウニ街道
Sea Urchin Cave is a Battle Cats stage in Sushi Island. It costs 100 energy and sends 15 enemy spawn lines — led by St. Pigge the 2nd as the boss — against a 120,000 HP enemy base, and clearing it rewards 80,370 XP. Its enemies carry the Red, Metal and Black traits, so cats that target them do the most work here.
