This sub-chapter brings out the potential of Zombie mechanics to a great extent. Without much knowledge on countering Zombies, some levels might be a little bit troubling - but overall, they're all still very much manageable when you know how the stage plays out and how to effectively counter these Zombies, even without anti-Zombie units.

Coffin Zoge: A coffin-shaped, Zombie variant of Wall Doge with higher health and slightly higher damage. Unlike most other Zombies, it can't burrow past your cats, but it revives with 100% HP an unlimited number of times.
Zamelle: A Zombie variant of Camelle. Similar stats to Camelle with no burrows, but can revive with 50% HP an unlimited number of times.
Miss Haka: A Zombie similar to Lord Gravey and Big Sal. She has similar stats to the former, but burrows infinitely like the latter, making her hard to fight with slow attackers. As a consolation, she has a high amount of knockbacks. While she can be easily bypassed while she burrows, she’ll eventually burrow up to your base if she or the enemy base isn't destroyed beforehand.
Sunfish Jones appears shortly after the stage begins alongside some Trolly Bloggers and eventually a Calamary. When the 2nd Calamary appears, Boraphim will appear soon after alongside a 3rd Calamary. Once you kill Boraphim, it won't be hard to dispose of the support.
