The giant plump caterpillar-like corridor is situated on the greenfield within the park. The extended body shape is formed with up-and-down arches as if it prostates freely among the greenfield. It signifies the rich ecological environment that is produced by Central Park. When people wander around happily and enjoy the moment, it will also be like they travel through a time tunnel with the expectations of the caterpillar's new future after its metamorphosis.
