At the start, 4-5 Jackie Pengs will come out one at a time at a moderate pace along with a few Doges. When the player hits the base, Xmas Pudding Cat comes out with a shockwave and Otta-smack-u. Shortly after, Rain D. comes out, followed by Camelle. Peons are constantly spawned, and Rain D. and Otta-smack-u continue to respawn.
Stall at the beginning with some Eraser cats while you max out the worker cat and save up money. Once you have max money or until the Jackie Pengs die, send out your ranged attackers (Dragon cat, Bahamut, etc.) along with your meatshields. Crazed Sexy Legs cat or any other wave attacker will help chip away at Camelle over time. Any cats that outrange Camelle will help too. Anti-traitless ubers will help as well because the boss is traitless. Treat this stage like the Crazed Cat stage, but easier. Since the boss has low range, anything that outranges it helps.
Stall with Eraser at the start until you max out your wallet. Once your wallet is full, send out Dragon Cat to kill off the Jackie Pengs. After that, go all out, sending everything along with continuous meatshielding. Alternatively, if you are struggling, you can wait for Dragon Cat to kill the Pengs and trigger the boss wave so you can lure it closer to your base before spamming. Once the boss is dead, proceed to kill Camelle. Tanky cats like Ramen cat will help with this. Once Camelle is dead, you've already won!
