A zone set inside a giant deciduous forest, which sees Sonic walking along large tree branches. It hosts flora and fauna in its backdrop, and an elaborate maze of trees in the foreground.
It appears in the Beta version of Sonic 2. In Act 1, right at the start of the level, the way is blocked, but with the use of the Debug Mode, the player can explore the little that was created of this zone. Act 2 is empty. The music that was planned for this level was used for Metropolis Zone instead, and this level even has the same conveyor belts from Metropolis Zone, and many people believe there is a connection between Wood Zone and Metropolis Zone.
