Dumpy Cave is the fifth stage in Bamboo Island.
- Line-Up: Li'l Mohawk Cat (40+), Li'l Eraser Cat (40+), Gato Amigo (35+), Li'l Macho Legs Cat (optional, 40+), Cyborg Cat (40+), Bombercat (40), Thaumaturge Cat (optional, 35+), Awakened Bahamut Cat (30), Holy Valkyrie Cat (29+), [Any Cat] (rec.30+)
- Power-ups: Speed Up (optional)
- Execution: Let the Doge Dark and Gory come to your base. Stall as long as possible trying to upgrade your wallet to MAX. Once THE SLOTH is halfway through the battlefield and you have a MAX wallet from killing any Gories and Doge Darks, you can keep pushing towards the SLOTH. Try not to spam as much Cyborg Cats as that could decrease the amount of money, but the Gories and Doge Darks may compensate that. When ever there's an opening and you're sure that THE SLOTH won't attack anytime soon, you can send either/both A. Bahamut and/or Holy Valkyrie to chip away at THE SLOTH's health. Repeat this process. If the SLOTH gets pushed behind the halfway point, it may be hard to clear the way and attack him directly, so you may need to let your cats die and let him progress. Make sure to stop any Gories or Doge Darks from attacking your base.
