Ilex Forest

Ilex Forest is an area of dense forest located in Johto, on the west of Azalea Town and south of Goldenrod City. At first, there is one man standing there, looking for his Spearow. He is asking you to find Spearow around the forest. You must do this quest because you cannot access to the other exit due to a tree which requires you to use HM01 Cut. When you found Spearow, Spearow will run away from you. Your job is to make Spearow run back to its owner by approaching it. The position you were interacting with, change the direction of where Spearow will run. After chasing, you will see another man beside the Spearow with the same man at the beginning. The man then awards use HM01 Cut so that you can access the whole forest.

One can battle Celebi in the Ilex Forest, in the Japanese version of Pokemon Gold, Pokemon Silver and Pokemon Crystal.
