Order Maiden (Insane)

Order Maiden (Insane) is the second and last stage is Maiden Awakens. Beating the stage unlocks Maiden Cat's true form, Olympienne Cat, assuming you do not already have it.

Before the Boss
As soon as the stage begins, a One Horn is sent out. Ginger Snache joins the fun soon after. From there, after about 15 seconds, a Teacher Bear and Ginger Snache appear, with a third and fourth Ginger Snache appearing a few seconds later.

Boss
With the fourth Ginger Snache, Sahori appears to crush you, or die trying! After about 45 seconds, a Celeboodle and H. Nah come out. From there, more Celeboodles, H. Nahs, and Ginger Snaches appear to support the boss until the level ends.

Strategies
Cat Lineup: Mohawk Cat, Crazed Macho Cat/Manic Mohawk Cat, Eraser Cat, Crazed Wall Cat/Manic Eraser Cat, Paris Cat, Crazed Sexy Legs Cat, Dancer Cat, Holy Valkyrie Cat, Bahamut, Ururun Cat.

What you want to do is use Paris cat and Bahamut to overpower the enemies. Raise the Worker Cat to level 3, and spam Eraser and Crazed Wall. Bring in Paris Cat and Crazed Sexy Legs when you can afford them. Dancer Cat acts as an attack support.

When Sahori attacks, the One Horn should be almost dead. Use its money to send in a Bahamut and raise the Worker Cat to level 4. From there, just keep spamming Paris, Eraser, and Crazed Wall. If you can get the Worker Cat to level 5, start spamming Manic Mohawk.

Use the money from defeated enemies to buy Holy Valkyrie, Ururun, and more Dancer Cats. Spam Mohawk at the end of the level along with your other meatshields, and you should win.
