Volcanic Defender is the fifth stage in Volkanos Volcano.
If the player doesn't have good defense units, the Shy Boys can knock down the Cat Base. Be sure to have enough income and spawn anti-floating Cats like Delinquent Cat, or Bahamut Cat and start spamming meatshields (Macho Cat, Wall Cat, etc.) and other units. If possible use the Cap'n Ahab combo, (whale cat and fisherman cat) to increase base health. Use a Rich Cat and then deploy Bahamut to kill the Shy Boys. Immediately start spamming meatshields after the shy boys are killed, and use a strong single-damage unit to knockback Bun-Bun. Continue meatshield spam.
You can also use Butterfly Cat to one shot the Shy Boys for max wallet at the beginning. They can also be a good help when fighting the Teacher Bun-Bun
Lineup: Meatshields (Crazed Cat, Crazed Wall Cat, Eraser Cat, Jiangshi Cat), Paris Cat, Maximum The Fighter, Doctor Cat, Sanzo Cat and Bahamut. Start by spawning a few Eraser Cats to stall Shy Boys for a bit, then start spawning Maximum to kill Shy Boys. When you kill 1 Shy Boy, use the money to upgrade your Worker Cat and save up the rest. When Bun Bun comes out, spawn Bahamut and your anti-floating cats. By now don't spam Maximum because Bun Bun can kill them in 1 hit. You can use a Cat CPU if you want to, but you can spam the cats very easily. Right now all you need to do is spam and try to keep your attackers safe.
Lineup: Eraser/Wall Cat, Crazed Wall Cat, Crazed Macho Cat, Dark/Brave Cat, Paris Cat, Beefcake Cat, Delinquent Cat, Bahamut Cat, Ururun Cat Start the level by spamming three Dark Cats to do massive damage to the Shy Boys. While your Dark Cats attack the Shy Boys, build up your Cat Worker. When the Bun Bun comes out send Bahamut to knock back the Bun Bun and kill The Shy Boys. When you have a lot of money, send out Ururun, but don't send her out when you just enough money because you won't be able to stall, then spam everything you have to take out the Bun Bun and win.
Lineup: Macho Cat, Samba Cat, Wall Cat, Paris Cat, Dragon Cat, a unit that has an effect on Floating (such as Lovely Yuki Cat or Angry Delinquent Cat), Valkyrie Cat, Bahamut Cat. Add other units such as meatshields or damagers depending on what you have.
Start by spawning one Macho Cat immediately and one Wall Cat afterwards. The three Shy Boys will push through them and hit your base. As long as you have upwards of 60K Base Health, you will survive this. Immediately spam Paris Cat as quickly as your money can handle it. After the boss shockwave, the Shy Boys should die. With that money, spam meatshields and immediately spawn Bahamut Cat and any other heavy hitters. Bahamut's first hit will knock back the Bun Bun to a safe distance from your base. Then, continue the battle as you would normally, by spamming meatshields and Paris.
- May require multiple tries to get it right. Force close and exit the game if Bun Bun hits your base.
Strategy 4 (for Four-Star difficulty)
Power-Ups: Rich Cat
Cat Line-up: Meatshields (Gato Amigo, Catburger, Jiangshi and/or Ramen), Sanzo Cat, Necromancer Cat, Paris Cat, Crazed Bahamut Cat, Ururun Cat (Use an additional useful Cat if you used three meatshields instead of four.)
Immediately send some meatshields. Once they die, let the Shy Boys hit your base, then spend money for a Bahamut Cat. Start your stream of meatshields and anti-Floating Cats once Bahamut is out. By this time, the Shy Boys should be nearly dead, and Bun Bun should be attacking your army. Once they die, they will completely fill your money, so make sure to upgrade your Cat Wallet before this happens. After they're dead, purchase Ururun and spam Paris Cats. By now you should have a lot of effect Cats out, and Bun Bun will be unable to advance because he will be Slowed or Frozen. Eventually, he will die, and you can safely finish this tough stage.
Strategy 5 (4-star)
Lineup: Defense Up (M), Cataur, Cameraman Cat, Sanzo Cat, Ramen Cat, Jiangshi Cat.
Note: If your combo does not fill the entire first row, I suggest adding a random cat to make spamming easier.
Note 2: My cats are pretty high leveled (Cataur and Sanzo are only lvl 30 but the other three are lvl 40+). If your cats aren't, I suggest using Worker Cat Wallet lvl Up combos instead of Defense Up so that you can better spam at the beginning (which is the most difficult part)
Note 3: I used Cataur because the enemies are all floating, but Cyborg works too.
Note 4: If your Ramen isn't your best available meatshield, feel free to replace it.
Start off with one or two Cameramans and start spamming Jiangshi, Ramen, and Sanzo (Jiangshi is first priority, followed by Ramen). They should be able to kill at least one of the Shy Boys. Don't be afraid if they end up hitting your base — it won't last long. With the money earned from the Shy Boy, level up your wallet a bit and just spam the five specified cats. If you do, you'll eventually win.
