192 Hours of Subway Rescue 

This day, when Gudu and Lanya took the subway to the Jam Music Festival, the subway braked suddenly, and the driver cat informed everyone that the railway was surrounded by strange grass, and the train was trapped in the tunnel! For a time, crying, shouting, and calling for help came one after another and all picnicked. At this time, Gudu discovered that these strange grasses were actually rubber grasses he had just developed. "It must be done by Gudu!" Everyone shouted angrily. In order to save everyone, and to prove his injustice, what solution can Gudu come up with? Can he succeed?
