Volcanic Defender is the fifth stage in Volkanos Volcano.
- 3 Shy Boys spawn after 0 seconds0f, delay 1.67~2 seconds50f~60f.
- Infinite Shy Boys spawn after 22 seconds660f, delay 40~50 seconds1,200f~1,500f.
- 1 Teacher Bun Bun spawns as the boss after 22 seconds660f.
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 attackers to knockback Bun Bun and continue the meatshield spam.
You can also use Butterfly Cat to one shot the Shy Boys for max wallet at the beginning, as well as being able to do massive damage when fighting the Teacher Bun Bun.
Battle: 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.
Strategy 2 (4-star)
Lineup: Gato Amigo, Catburger, Jiangsh Cati and/or Ramen Cat, Sanzo Cat, Necromancer Cat, Paris Cat, Crazed Bahamut Cat and Ururun Cat. (Use an additional useful Cat if you used three meatshields instead of four).
Battle Items: Rich Cat (required)
Battle: 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.
