"Toy Box Series: Express Fleet" Express Fleet (Volume 1) is the first episode of the JO Toki Manga Toy Box series. The main plot revolves around how, in the dead of night while children are fast asleep from the exhaustion of the day, the dolls in the toy box are busy constructing a railway. With crayon sleepers and xylophone iron bridges, they sing construction songs in chorus until the railway is completed. From the toy town to the dining car, the express train sets off amid joyful cheers. The train journey continues, passing through tunnels and crossing iron bridges. Suddenly, a loud crash—derailment and collision! It was the work of the dining car mice, who were displeased by the arrival of the toy train. The mice trap the startled dolls in mousetraps, kidnap a beautiful female doll, and flee. A major crisis! The entire toy nation mobilizes, and a great naval battle begins between the mouse boats and the toy army's fleet in the backyard pond.
