Conservation Society is the final stage in Galapa-Goth.
This stages introduces a new threat called Henry.
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.
When you spawn your expensive units, time them so that they spawn after Henry uses his attack so they can reach his blind spot.
Any units with freeze immunity, notably Li'l Eraser Cat, talented Riceball Cat, Delinquent Cat and certain Ubers can make the stage considerably easier.
Lineup: Cat, Eraser Cat (20+14), Manic Eraser (20), Manic Mohawk, Pizza cat (35), iCat, Bombercat, Crazed Whale Cat (20), Island Cat (20+18), A. Bahamut (30).
Start by upgrading your worker cat to lvl. 4, let the Capy go to your base, then start spawning meatshields with everything except Bahamut. When you beat the Capy and hit the base, Henry will come out, first you should try defeat his support and spawn A. Bahamut after he used his attack. If you spam everything, he will be stuck on one place and eventually with your second A. Bahamut you should beat him.
