This stage might be cycled around like the other awakening stages (no confirmation for now).
The battle starts with Those Guys and Hippoe being spawned from the enemy base, it'll continue for a bit. When the enemy base HP goes down to range near 98303-98920, Value Meal Cat (enemy) will appear with a boss shockwave, accompanied by Kang Roo. Then the enemy base will continuously spawn Kang Roos accompanied by Hippoes and Those Guys.
The stage is pretty straightforward, just send a wall of Wall Cats to stall the enemy or spam a lot of heavy hitters like Paris Cat to finish the stage quickly. Even the boss isn't that much of a threat.
