Note: all COTC treasures for starred aliens are mandatory
2 cats for a worker up combo, Island Cat (20+60), Castaway Cat (30+2), Major Leaguer Cat (30), Eraser Cat (20+60), Catellite (40+9), Weedwacker Cat (30+5), Housewife Cat (40), The Kitty of Liberty (30)
Holy Blast is a good Cat Cannon to use just to avoid Znaches messing up your beginning stack; alternatively, use Breakerblast.
Lure the UltraBaaBaa's to the base and stall with Catellite and Eraser Cat while stacking Housewife Cats, Major Leaguer Cats, Weedwacker Cats, and, if you have money, a Castaway Cat.
When the third UltraBaaBaa approaches, spawn just one Kitty of Liberty. You always want to have a few enemy units in front so that when the Le'Solar approaches, your units do not enter Le'Solar's range.
Spam meatshields, Housewife, Major Leaguer, and Weedwacker Cats with a single Kitty of Liberty if you feel you are getting overrun. Although Catellites should be used, it's best not to spam them and pretend they have a slower recharge speed. Use a Holy Blast to stop the first Znache from burrowing under your troops. Buy Surfer Cat (or any Ubers you might be bringing) if you have excess money.
Continuing with the aforementioned spam should win you the level, because, eventually, a critical mass of Housewife and Major Leaguer Cats will vanquish the Le'Solar and knock out Znache before it burrows, while your Weedwacker Cats help the Housewives stall the Zyclones.
