- Another Gory Black spawns after 80 seconds.
- Another Angelic Gory spawns after 100 seconds.
"Do not even try if you are not prepared."
The above advice is pretty helpful when you think about it. The main difficulty of the stage is the Le'noir and the Chickful A: you don't really get much money at all after 2 minutes. Use 3-4 meatshields, Ramen Cat, a barrier breaker cat (i.e., Cat of Liberty,) Pizza Cat or another hefty damage-dealing cat, and 1-2 long ranged attackers like Awakened Ururun or Bahamut Cat.
Upgrade your worker cat to level 4-5 in the beginning, begin to stall a fair distance (800-1200 pixels) from the base, and use Pizza Cat and Cat of Liberty sparingly to get through the initial wave of Gories and UltraBaaBaas, as they will push hard if you mess up. Then, spawn your long ranged attackers and meatshield for 5 gruesome minutes. Eventually, everything should die.
Using Awakened Bahamut and Bombercat can be difficult at times because the Kroxos spawn very frequently, but could be done if your timing is impeccable. Using an anti-black or anti-angel Uber like Vars or Kasa Jizo makes life extremely easy, as well as using long range ubers like Megaphrodite or Unknown Cat along with a fast attacking unit like Ururun.
