Strategy 1

Lineup: Biohazard + Bony Bone, Jellycat, Pizza Cat (Wave Talent at level 10), Manic Eraser Cat, Eraser Cat, Bombercat, Octopus Cat, Supercat.

The entire gimmick of this stage is having wave attackers, but trying to stop you from using Wave Shields. So the solution, of course, is to freeze the things trying to stop you. This entire stage revolves around getting Bombercat to freeze the Dark Otters, as they will melt your Octopus Cats in seconds. Use Pizza Cat to kill the first Doge Dark, then stack Bombercats on the Wall Doges. From there, stack Pizza Cats on the Wall Doges.

When the Two Cans approach, Dark Otter might've been knocked back already, so you need to get Bombercat to be hitting Dark Otter at all times. When Octopus inevitably dies, send Supercat to block the waves in the gap it takes to get another on the field. Use Jellycat whenever available, as it can hit almost anything in this stage. Rinse and repeat until the Two Cans are done spawning. Kill THE SLOTH, and win the stage.
