Conservation Society is the final stage in Galapa-Goth.
This stages introduces a new threat called Henry.
Bring shorter ranged units, but not too short ranged.
The challenge of this stage is that Henry will freeze your cats as they come in, making them unable to do things. The Dark Otters and Gory Blacks can plow through your meatshields while the Capies can kill your expensive, strong cats in a couple of attacks.
Bring a Cat CPU to help with this.
When you spawn your expensive units, time it so that they spawn after Henry uses his attack so they can reach his blind spot.
If you have any Mitama (Gothic Mitama, Mitama the Oracle), use her in this stage as she is immune to freeze. She will pass through Henry's range like nothing if there are no peons in front. With proper meatshield and Titan (Crazed Titan preferred) to protect her from peons, she will be able to kill Henry
Tip: The ideal meatshield for this stage is Li'l Eraser Cat since he is immune to freeze, which means that you can still have meatshields without the risk of them getting frozen.
