Once the Doge Darks come out, spawn in Macho and Wall Cat to stall them as much as you can. Once you have enough money, spawn in Bahamut Cat BEHIND the base. Once you have killed them, keep up the spawning of Macho and Wall, along with Sexy Legs Cat and Dragon Cat. Sets of 3 Doge Darks will attack while you approach the base. Once your units reach the base, Dagshund will appear. Keep spamming the cats mentioned above, along with any other hard hitting cats. Once you have killed the Dagshunds, you can attack the base harder.
