This is the only level in Chapter 3 of Annihilation City's collaboration stages.
- Strategy 1: (requires Rare Capsule Cats and Crazed Cats) Cat Line Up: Crazed Macho Cat, Eraser Cat, Crazed Wall Cat, Crazed Sexy Legs Cat, Paris Cat, (Crazed UFO Cat, King Dragon Cat, Crazed Dragon Cat), Crazed Bahamut Cat and Ururun Cat. Begin the battle and spawn a couple of Paris Cats to attack enemies, Crazed Sexy Legs Cat to attack Pigeons and the three meatshields whilst building up money. When the bosses appears (Yuki and Teacher Bun Bun), mass produce Paris Cats as well as meatshields. Bahamut Cat and Ururun Cat should be spawned once the boss appears (if player has a lot of money), but they have shorter attack range than Yuki, leaving them vulnerable but they may still land a few hits on other enemies before they die. Score: around 900.
