The stage mainly consists of Red Enemies. It begins with some B.B.Bunny, St. Pigge the 2nd, and other Red enemies like One Horn. The boss is a Bore with a 150% buff. He can plow through your lines without enough crowd control.
Bring Island Cat, Crazed Whale Cat and Dark Cat/Crazed Brave Cat. Pirate Cat and other anti-Red Gacha Cats will be super helpful here. The buffed Bore can be annoying, but you just need to meatshield!
