Ogre Island is a special stage available on the 21st of every month if the player has previously completed all Crazed Cat stages. Completing this stage unlocks the True form of Crazed Fish Cat. Using Cat Food to continue the battle is not allowed in this stage.
At the beginning, one Manic Island Cat is sent, with many Crocos as support. Soon after, 3 Manic Islands and a few more Crocos are sent. This formation repeats until the base is hit; then, a Berserkory and 6 Manic Island Cats appear! After Berserkory dies, the Manic Island Cat spawn rate increases even further. Brollow is also occasionally sent in groups of 3.
- Use a similar strategy to Fish Hell, but replace the Crit Cats with Dread Pirate Catley or another strong anti-Red Cat. More DPS is needed against the tougher Islands.
- Using three spammable Cats makes Berserkory more likely to miss. Stack Crazed Dragon Cat, King Dragon Cat, Macho Legs Cat and Manic Macho Legs to kill the Berserkory quicker.
This strategy is much different then fish hell. You want to bring 3-4 meatshields with Ururun Wolf and Pirate Cat's true form and start spamming and also bring Bahamut and keep on spamming and your done do NOT bring awakened Bahamut because he has low range and can die easily. The rest of the deck is optional but if your gonna bring a uber make sure you bring rich cat.when Berserkory comes out he'll be knock backed alot if you have enough Pirate Cat's and Ururun Wolf's it should be easy.
Strategy 3 (theory/not tested)
- Power Ups: Rich Cat
- Start off by saving up for Diabolic Gao also start meatshielding, Diabolic Gao can two shot the Manic Island Cats and it's attack range is bigger than Manic Island. After that, send Gao out. When they hit the base, send Cat Machine Mk3 as well as Dread Pirate Catley. Now, Repeat steps until you complete the stage.
