No Gacha Strategy (Thunderbolt Cannon Needed)
- Crazed Cat Cat, Mohawk Cat, Crazed Wall Cat, Eraser Cat, Maglev Cat, Crazed Fish Cat, Crazed Titan Cat, Jamiera Cat, Awakened Bahamut and Heroic Musashi.
- Note that you don't need all of the units in this list.

(Note that this strategy also works on four star, just replace the meatshields with Special ones, and replace Maglev with Awakened Bahamut Cat)
Octopus Cat Strategy
- Any Money Up and/or Attack Up combo, Octopus Cat, Awakened Bahamut Cat, and anything else you want (high Dps units)
Send out something to trigger the Doge Cannon Wave, then send Octopus Cat after the wave passes. Make sure to keep spawning Octopus Cats, and spawn an Awakened Bahamut Cat when you can. After this, spam your other high Dps units to kill the base.
- This level has the third most magnified assassin bear in the game, beaten by Veggie Friends in second place and Forever Fishing In first.
