When the base is hit, Henry appears as the boss. Three Shy Boys pop out with about 15 seconds between each one and they are at a high strength magnification of 2000%. The Doge Dark spam is now more effective due to a bigger enemy limit.
Lineup: Manic Eraser Cat (40+), Drone Cat (30+), Skelecat, Hyper Mr., Necro-Dancer Cat (30+), Li'l Eraser Cat (45+), Jiangshi Cat (30+), Sanzo Cat (30+), Cyborg Cat (40+), Slapstick Cats (35+)
Drone is replaceable by Cameraman. Skelecat, Hyper Mr., and Necro-Dancer are all present for their combo, but Necro-Dancer can be used in battle.
Cat Cannon: Curseblast or Breakerblast
Battle Items: Cat CPU (recommended)
Start off the battle by stalling the Doge Darks with your meatshields and then save up for Slapstick Cats. Once you get one Slapstick Cats out, don't spawn anymore and use the money from the Doge Darks until you get to max worker cat, stop spawning meatshields and let the Slapstick Cats die if they are pushing to far towards the base though. Also use this as a opportunity to get max money as well. Once you are at max worker cat and money, send out everything and money shouldn't be an issue once the boss wave hits because of the Doge Dark spam. After this it's really just complete spam all your units due to having infinite money, even the combo units, (Necro-Dancer can actually help due to him being able to freeze the Shy Boys occasionally) but here is some more things you might need to know. You will be struggling for money a bit in the beginning of the boss wave, if you are using a CPU, turn it on once you start killing the Doge Dark spam. Henry will most likely kill your initial stack and the Shy Boys will push closer to your base when this happens, but all this means is that not as many units will be frozen by Henry, even if it means your base is being hit, but Henry's damage is low so it's negligible. Once Henry pushes towards your base, only two Shy Boys should be there and once one of the two left dies, the other one will follow shortly. After killing all the Shy Boys and Henry all you have to do is kill the Doge Dark spam, and then then you will have destroyed the base and won!
