Send out Sexy Legs Cats and Dragon Cat after about 5-7 Those Guys appear. Doge Darks will come out so start spawning Wall Cats as well. After defeating the first Doge Dark, you may want to start spamming Macho Cats on top of your Wall Cats because Gory Blacks will spawn soon. Keep on meatshielding and sending out your attackers, Sexy Legs Cat and Dragon Cat.
You might want to spawn Bahamut Cat out as your cats start hitting the castle. A few more Gory Blacks and Doge Darks along with The Face will spawn with the boss, Dark Emperor Santa. Keep meatshielding to stall the boss, and use your long range attackers to stack up damage from a safe distance. Use any Uber Rare Cats you may have to finish the level faster. Make sure to fire the Cat Cannon to interrupt Dark Emperor Santa's attack, although you must time it well. Once The Face and Dark Emperor Santa die, you are free to claim your victory!
