Several Coffin Zoges come out in the beginning of the stage, followed by a Tackey. After around forty seconds, Dark Emperor Nyandam will be sent out. The Coffin Zoges will protect the Tackey and Nyandam for a majority of the stage. Occasionally, a Zory will come out of the base and burrow through your frontlines. Once the third Zory is sent out, no more will appear on the stage.
It is recommended to bring at least one cat with the Zombie Killer Ability, such as Kite Cat or Hyper Mr. This will allow you to dispatch the Coffin Zoges quickly. After all 3 Zorys are killed, you can feel free to spam your Zombie Killers. If you send them out beforehand, they will likely be killed by the Zorys when they burrow. The Tackey can be killed early on if you lure it and kill it with a high-DPS unit such as Awakened Bahamut Cat.
