- When the base reaches 99% HP:
Save up for max money in the beginning. When you hit the base, lure both the Shy Boy & Cyberface to your base, and send a cat right before they reach your base. The moment that cat dies and Cyberface's shockwave has passed the back of your base, send in a 100% critter, preferably one with a short attack Animation such as Sunny Neneko, but others can work. After that, get the Shy Boy off your base immediately via Breakerblast and stall him with meatshields while draining his health. After Shy Boy dies, it's just meatshield & chip.
