Head Shaker is the fifth Crazed Cat Stage. It appears on the 15th of every month.
At the beginning of the battle, a Crazed Cow Cat will be spawned with a few B.B.Bunnies. When the player damages the enemy base, a group of Crazed Cow Cats will appear. The spawn rate of these Crazed Cow Cat also increases.
Crazed Cow is by far one of the easiest Crazeds to beat. All you truly need is The Flying Cat, Bahamut, and meatshields.
If you don't have Crazed Tank, you may want to replace it with another meatshield. Bring Crazed UFO if you have it as one of the area attackers. Bahamut should be high level.
Stall the first Cow with Wall to get enough money for a steady Flying Cat spam. If your tanks are strong enough, only use them, as a small stack of Mohawks or Crazed Cats will tear down the first Cow quite rapidly. When it comes time for the boss wave, Crazed Gross, Bahamut and the last unit if you picked an Uber/Ururun should be summoned first, as you, depending on your unit levels, will need them all to get a hefty stack of area attackers. If Bahamut is level 30, you'll have no problems with the initial stack. Paris Cat and Cameraman Cat can also demolish this stage, so if you have them, use them (Mer-Cat is only useable in True Form).
Strategy 2 (Ft.Warlock and Pierre, cheese)
- Lineup: Crazed Bahamut Cat (Lv. 30), Eraser Cat (Lv. 20+20), Mohawk Cat (Lv. 20+20), UFO Cat (Lv. 20) Gato Amigo (Lv. 30), Warlock and Pierre (Lv. 30 minimum)
- Items: Rich Cat is highly recommended.
The goal of this strategy is to get Warlock and Pierre to hit the base without bringing out the horde. Stall the Crazed Cow until you can get Warlock and Pierre out, then kill the Cow with any attacker slower than Warlock and Pierre and watch as they one-shot the base.
Alternatively; if don't have level 30 Warlock and Pierre, you can stack several low-level Warlocks or other units with target only on the first Cow, as long as you don't spawn any attackers.
