이번에도 제로니모의 모험은 특별하게 시작된다. 지하철에서 유령 고양이가 발견되었고, 그래서 사람들이 모두 지하철을 타지 않기 시작했기 때문이다, 과연 제로니모 일행은 이 고양이의 정체를 밝혀낼 수 있는 것일까?
A lot of mice wanted to catch the cat, so they started to make a lure for cat. They though cat will like that box of food, huh? And Sally, who is the most big rival of Geronimo also started to find about the phantom. Why it started to appear? Was there a problem? Or is this a real cat?
Professor Paws Von Volt is one of the greatest mouse in the world. He invented a lot of thing, and he also saved the last Yeti, who was going to die. Sally found his laboratory and he had to hide it, and he decided the place for subway.
If he had to save his laboratory, than he had to chase mice away. So he used a robot cat and sound, and people started to not to get on the train. This was all Sally' fault, and Geronimo could get the story on the newspaper about him. I'm glad Geronimo can eat n the France restaurant, again!
