==Strategy ==
Note that Slime Cat is fairly good here if you hit the base with it (for 4 star) the resulting wave will instantly kill the first Brollows and Pigeon de Sables (assuming Slime Cat is level 30 or above.) 
Anti-Floating tanks such as Octopus Cat and Divine Kai will help immensely, and almost guarantee a win. 
===Strategy 1 (No Gacha)===
Lineup: Crazed Macho Cat, Eraser Cat, Crazed Wall Cat, Crazed Sexy Legs & Macho Legs Cat, King Dragon Cat, Jamiera Cat, Crazed M. Titan Cat, Holy Valkyrie Cat, Awakened Bahamut
Begin the battle by spawning a Jamiera Cat. He should be able to hold off the Pigeon de Sables. When the base is hit, as quickly as you can spam meatshields, Macho Legs, Crazed Sexy Legs, and the tanks (King Dragon, Jamiera, etc.). After some time, spawn Holy Valkyrie. After she dies, send out Awakened Bahamut once Mr. Mole has finished his attack animation. Bahamut will most likely die quickly, because of Mr. Mole. The enemies should get very close to the Cat Base, so expect your base to take a couple of hits. After some time, Mr. Mole will get knocked back. Just continue spamming your units until Holy Valkyrie is available again. Try to hold out some more, and the Brollows and Pigeon de Sables will stop spawning. Because Tackey and Mr. Mole are both long ranged, and there are no close range units, the level should stop being too hard. Even if one cat enter the enemies' "blind spot", they will slowly die.
Now all that's left is to destroy the Enemy Base! Onward to Victory!
===Strategy 2===
Lineup: Manic Eraser 40, Butterfly Cat 30, Can Can Cat 40, Octopus Cat 35, Zamboney 30, Crazed Whale Cat 30, Maglev 30, Manic Jamiera Cat 30, Grandmaster Cat 30, Awakened Bahamut Cat 30
Cat Cannon: Iron Wall, Normal or Breakerblast.
Stall the initial Pigeon De Sables with Octopus, spawn another when the first dies and use this time to upgrade your Worker Cat to a level you see fit. Once Octopus is nearing the base, spawn out everything you can as the Brollows will otherwise clip through your units and to your base, making you lose a lot of ground. Once you hit the base, spawn out everything you can except for Grandmaster and Awakened Bahamut, Grandmaster is not good against Brollows as waves make Brollows due to their attack more often, and Awakened Bahamut should be saved if the Pigeon De Sables stack up to much and you need to clear them out all at once. After that it's really just spam, not really much else to say other then that this is an endurance match more then anything, outlast the Pigeon De Sables and the Brollows and taking out Tackey and Mr. Mole will be easy as pie, try to make sure you time your units to get into the blindspot of Tackey and Mr. Mole before the Brollows and Pigeon De Sables end, but after the Pigeon De Sables and Brollows stop appearing, you no longer need to really time anything and after that, you have won the level!
===Strategy 3 (4 Crown)===
Lineup: Riceball, Madam the Savannah, Put On Ice, Li'l Eraser 50, Jiangshi 40, Camera 55, Cyborg 55, A. Bahamut 40, Doguemon 30 (Replacement: Ultimate Mecha-Bun 30)
Start off by sending a Green Shell which should be able to stall all 4 Pigeons. Send more Green Shells to stall/kill all the Pigeons and max out your Wallet.
Once you hit the base, start to spam meatshields + Cameraman + Riceball + Madam + Cyborg. The line will retreat gradually. Pigeons and Brollows will be killed in this process and by time the enemies push to your base, the wave will have died down.
After all Pigeons and Brollows are dead, spam Riceballs and nothing else. Find a timing to send in A. Bahamut, which hopefully will knock back enemies and prevent them from hitting your base any more. Send in Green Shell will further make sure they won't hit your base again. From this point on, just spam Riceballs to win. If A. Bahamut dies send out Doguemon.
== Strategy 0(No crown) ==
Lineup: Little Warriors + Étoile minimum + Green Shell Cat + Octopus Cat + A.Bahamut 
[bring Wave attacker (150<"Your unit range"<350) to win faster]
All cat lv 30+, Octopus 40+
Start off by sending a Green Shell which should be able to stall all 4 Pigeons, spam Octopus to the end of stage
Spawn 1 Green Shell after shockwave to stop the Brollows hit your base (or not if you want to do something else)
When 13 Brollows die, timing and send A.Bahamut 
Easy win :) (just joking but it actually works)
