Upon capturing the Cat Bus:
Pocket Ball, GO!
After you exit the Cat Bus, it meows and purrs at you. Such a nice creature! Much nicer than you...
You reach for your Pocket Ball while you pat the purring Cat Bus. With a sudden movement you throw it in the Cat Bus' soft belly fur. It disappears in the creature's blubbery body for a few seconds. A big flash emerges from the creature's fur and it gets sucked into the Pocket Ball. It wiggles a little, but quickly stops. Hurray, you've caught the friendly, Japanese Cat Bus!
