A few very weak peons will spawn to distract you. Once the base is damaged, Teacher Bun Bun (Floating) will spawn followed by J.K Bun Bun (Red/Floating) and then Bun Bun Black(Black/Floating) and lastly Bun Bun Symbiote (Alien/Floating). Peons will constantly spawn through out the game.
- Cats: Crazed Macho/Manic Mohawk Cat, Eraser Cat, Crazed Wall/Manic Eraser Cat, Jiangshi Cat, Sanzo Cat, Cameraman Cat, Tathagata Cat, Holy Valkyrie Cat, Bahamut Cat/Crazed Bahamut, and Ururun Wolf.
At the beginning of the level, let the peons hit your base, and upgrade the Worker Cat until it's level 8 and you have maximum money. From there, spam your first 3 meatshields, Sanzo Cat, Cameraman Cat, and Tathagata Cat, and spawn Holy Valkyrie Cat.
When the base is hit, Teacher Bun Bun will appear, but he should be no match for the endless slowing effect of Sanzo Cat and the high anti-Floating damage of Cameraman Cat. When J.K. Bun Bun comes out, start spamming Jiangshi Cat in addition to your other meatshields. You should also send Bahamut and Ururun Wolf at this time if you have enough money. Bun Bun Black isn't much of a threat here, so there's not much to say about him.
The scariest part of the level is the Bun Bun Symbiote. One shockwave will total your entire stack of Sanzo and Cameraman Cats, not to mention all your heavy hitters. Tathagata Cat's weaken effect comes in handy here.
Once all the Teacher Bun Buns die, you are free to win the level.
- Constantly spam Li'l Tank Cat/Li'l Wall Cat, and you'll win for certain. The beginning peons will take up so much space that Teacher Bun Bun will be unable to spawn, making the level a cakewalk. To speed it up, you may also want to send Maglev Cat and Awakened Bahamut once all the peons are behind the base.
