This stage is quite challenging, consistent Brollow spam backed up by two Hackeys is enough to defeat even the most skilled of players.

Strategy 1

Lineup: Mohawk Cat, Manic Mohawk Cat, Eraser Cat, Manic Eraser Cat, Cameraman Cat, Fishman Cat, Octopus Cat, Seafarer Cat, Pizza Cat, Cyberpunk Cat.

Cannon: Iron Wall

Start of the battle by sending occasional Manic Erasers, not too far apart but not to quick in succession either. Try and line up the Hackeys together, and once you achieve that, lure them to your base. Your goal here is to sync the Hackeys which will majorly decrease the difficulty of the stage. During this time a pool of Crocos will build up, clogging the enemy limit. This also means that once they are killed, the Brollows will start to spawn, so get ready.

Start deploying your anti-Floating Units first once the Brollows make their way onto the battlefield. These include Cameraman, Fishman and Octopus Cat. You can add Seafarer to the mix when the time is right. Timing Pizza Cat is much riskier as its slow speed means it is more prone to be sniped down by the Hackeys so keep that in mind. Throughout all of this, one unit still has yet to be spawned, Cyberpunk. The key here is to only spawn Cyberpunk when you are pushed against your base. Spawn it any time else and it will get sniped down. Once the Brollow wave dies down, the victory is yours.

Strategy 2 (Ft. Healer)

Lineup: Bento Special + Reindeer's Gift, Cameraman 40+5, Li'l Eraser, Green Shell 50, Healer Cat CC, Golfer 35.

Items: Sniper (Mitigates RNG)

Spawn Green Shell immediately and spawn Healer when you hit 500 cash. Green Shell should hit the first Hackey and it will then get hit by the Sniper. After Sniper fires once, turn it off forever, if you don't have sniper there is a chance that the Crocos wont get frozen and the run will be dead.

After a bit, Healer should enter Hackey's blindspot. When Green Shell is recharged, send it out immediately. If all goes well the Crocos should kill Green Shell just after the second one arrives. Finally, spawn Healer 2s after both Hackeys attack. Healer should sneak into the blindspot and permafreeze the Crocos. Be sure to send another Green Shell though if they aren't permafrozen. After that, you just spam Golfer until the base goes down.
