Teacher Bun Bun (ぶんぶん先生 bun bun sensei, Bun Bun Teacher) is a Floating enemy that serves as the final boss encounter of Empire of Cats Chapter 3, and sometimes appears in the Stories of Legend.


This is the strongest and most deadly enemy in the Empire of Cats Chapters. It is first seen in Chapter 3-48, known as the Moon (Chapter 3-48) in the English version. Some Stories of Legend levels will also have Teacher Bun Bun and his colored variants. He has a massive 399,996 HP (that's nearly 1/2 of the Moon's base) and 9,000 damage in Chapter 3 - Moon. Some say he is impossible to defeat, but he can be defeated with the proper strategy, an example being a continuous "meatshield" spam (e.g Basic Cat, Tank Cat, or Boogie Cat). Also is easily countered by numerous Paris Cats and Dragon Cat stacks, with proper meat shield spamming.

The video does not show how to beat this fatty correctly. The wall cats must be lvl. 40 or higher in order to survive two blows from Bun Bun.


A fair amount of people fall into the trap of spending cat food in order to defeat Bun Bun when they first encounter him. Although, Bun Bun is the hardest boss in EOC, with proper strategy and lineups, you can defeat him without spending any cat food.

Before attempting, it is highly advised to have 100% treasures or at the very least, activate them. Save your cat food since you might regret spending it later. Patience and being rational is the key to winning. Additionally, there will be much harder challenges to overcome in future stages.

Strategy 1 for first encounter

Lineup: Macho Cat, Wall Cat, Sexy Legs Cat (optional), Dragon Cat, True Valkyrie Cat ,and an Uber Rare if you have one (although it's not impossible without an Uber).

Note: All your cats MUST be lvl 20 and you MUST have 100% treasures on Energy Drink, Giant Safe, Relativity Clock, Legendary Cat Sword and Shield for all Chapters of Empire of Cats.

  1. Lure the Kang Roo near the Cat Base.
  2. Once the Kang Roo is dead, start spamming your Macho and Wall Cats. If you can, also spawn True Valkyrie.
  3. Once you have enough money, start stacking Dragon Cats.
  4. You should have 2-3 Valkyries at this point. Do not stop meatshielding and stacking Dragons.
  5. Once Bun Bun appears, begin to meatshield (stall) in a way where Bun Bun won't advance ,and hit both of your meatshields in one attack.
  6. Bun Bun has 10 knockbacks, so count them to see how close he is to death.
  7. Try the best you can to not make Bun Bun hit the Dragon stack. Also spawn Valkyrie if she recharges.
  8. Do this until Bun Bun is dead. Once he is, excellent work, you have now completed Empire of Cats, unlocked Bahamut Cat, unlocked the Catfruit storage, and are able to progress further in the game!

Strategy 2 for first encounter

Lineup: Basic Cat, Tank Cat, Catburger, Dragon Cat, Titan Cat, True Valkyrie Cat + optional Uber Rare rare / Sexy Legs / Kotatsu / cheap cats.

  1. Save money, then deploy some Tank Cats. 
  2. Summon a Valkryie Cat and use cats to protect her. 
  3. Upgrade your Worker Cat to max, then get a full wallet. 
  4. If you are close to the enemy base, stop spamming cats.
  5. Once you have money, summon every strong cat you have. 
  6. When Teacher Bun Bun comes out, deploy every cat you have (you should have at least 3-4 meatshields). 
  7. Call God for knockback if Teacher Bun Bun is close to your ranged attackers. 
  8. You should win if you have good cats; Congratulations!

Strategy 3 for first encounter

NOTE: you must have three or more meatshields and no treasures needed! (LVL. 15+ and also requires a wall cat LVL.25)

Recommended meatshields: Macho Cat, Wall/Eraser Cat, and Samba Cat

  1. By the time Kang Roo hits your cats, you must have 4 or more wall cats.
  3. By the time mooth comes out, use 2 of your meatshields.
  4. Slowly upgrade your wallet to MAX.
  5. When Bun Bun comes, use all 3 meatshields and have at least 2 Valkyries.
  6. Your Dragon Cats would knock back Bun Bun insanely quickly
  7. Make sure that your meatshields are tight, or else they would be plowed down and killed.
  8. Do this until Bun Bun dies.

Strategy for late game encounters

For now, you should have more anti-Floating units in your arsenal that can help you. Strong units like Catman and stacks of heavy hitters like Dragon Cat or Cyborg Cat can deal enough damage to knock him back and prevent him from attacking your long-range units, or units with slow/freeze abilities can greatly help to win against him. Megidora is very helpful against him and his variants, as his knockback ability can prevent him from getting close to your heavy hitters, and his slow ability can keep your line safe. Kai can also tank many hits from him (especially in True Form), and deal heavy damage if she gets close enough to attack him.

Uikichi A "traditional" way to beat Teacher Bun Bun in Chapter 3-48

  • Teacher Bun Bun is the only enemy boss that doesn't has a variant in annual events as well as collaboration events (like The Face - Princess Head).

  • Teacher Bun Bun used to be Floating/White-type, but it was changed to just Floating in update 5.10, when Shadow Gao was released.

    • This was pretty great for a while. I liked it for some time.  This is kinda just a meme now and I feel like its needless to have this here now
