For all Chapters - Upgrade your Worker Cat. When the enemies get close to the Cat Base, send out a couple of Wall Cats. Just wait for your money to go up, and when Sir Seal and Gory appear, start spamming meatshields, Brave Cats, UFO Cats and Whale Cats. When you kill them, Jackie Peng should be no problem. After that, send out Mythical Titan Cat and you will be good to go.
The man that serves as the enemy base is most likely supposed to be Diego Maradona.
