Wormholes are circle shaped green holes. They are composed of swirling green gases, with light green gases in the center and dark green gases on the outer rim.
Wormholes warp the new born sun to another other wormhole in the level. This allows the new born sun to access an area inaccessible by other means, such as past a wall. The player must be careful to not accidentally lead the new born sun into a wormhole unintentionally, as enemies or hazards could be waiting on the other side.
