0:00 - Iwa Rock Reef
If you're used to the nothing buffs on Starred Aliens in previous subchapters, a quick reminder that this is where it ends. There are two ways of going about this stage. The first is to Warp enough things behind Professor A that you can push all the way to the base and kill it. However, this might become a problem since Star Peng here is incredibly buffed. The alternative is to just outlast the stage as it is. Dumpling is extremely useful here for getting rid of the Gardeneels while your other units deal with the frontline. The Star Pengs are limited, so once they're gone you have a clean shot at Prof. A. Or you can use an Uber to snipe it.
2:29 - Nautilus Tomb
This stage becomes hell with the boosted magnifications. Your goal here is to constantly juggle the Mr. Moles to prevent them from ever attacking your CC stack for the Gravey. Naala and Jagando are great for this and Cyberpunk will help to stall even longer. Be careful with your Dumpling sends since they can trigger Mr. Mole attacks before you expect them. Rich Cat is highly recommended to be able to afford Camera spam to hold off the peons. Once the Moles are gone, you win.
4:46 - Lost Sailors
Royal Guard makes this stage WAY easier than it's ever been before. Stack Guards on the Oldhorn and Mesocyclones and you'll just steamroll the stage. Fishman is definitely a better bet than Cataur for The Face getting rushed down, but as you can see here, Royal Guard already does plenty of damage.
5:53 - Caged Carp
You want to abuse UltraBaaBaa here to stack piercing damage and take out the other enemies on the stage, but UltraBaaBaa itself has real damage now. Letting them stack is not an option and bringing Liberty would very quickly let the UBBs die and your stack push into Lenoir too early. Instead, you want to use Supercar's Barrier Breaker to your advantage since it's likely to pop a single UBB then die. From there, Soractes, Fiend, Pizza, and Catjobs can deal with the other enemies. A good Catjobs Surge will singlehandedly win the stage, so bank on that.
7:35 - Quay of Camels
The stage gives you infinite time to stall for wallet, so do that. The boss wave is mostly just making sure the Shy Boys don't push into your anti-Relics and letting them carry against the rest of the stage. Octo, Can Can, Courier, and Fishman have the Shy Boys under control.
9:10 - Endless Dead Zone
Do not underestimate how strong the LeMurrs here are. They can and will destroy you if you don't bring multiple Alien stallers. Make sure the Axolotys don't take too much space. The Zombies should be fine as long as you can keep the LeMurrs under control and don't let them stack up. Seafarer can help Royal Guard chain down LeMurrs.
