The Forest Map (aka Cove Map) is an award in Club Penguin. It was available before the Cove Opening Party. You had to find the map by going to the Ski Hill. It will fly into the signpost. When you clicked on it, it flew away. Follow it down to the Ski Village. When you click it, it flew away again. Then continue to the Dock and Town where you will find it on one of the lights in front of the sign for the Night Club. When you click it, it flew away one last time. Go to the Snow Forts and you will find it underneath the Clock Tower. You can then click on it to add it to your inventory.
The only time it was available was before the Cove Opening Party. One day, a penguin was playing Jet Pack Adventure and miscalculated his landing. He ended up in an uncharted wilderness and heard the sound of the ocean. Approaching the area, he discovered an uninhabited beach, and made a sketch of its features and location. His friend located him and they explored the beach. Unfortunately, on their way back, the map was blown out of the penguin's grasp. The map was lost, but after a massive search, it was found.
