Pokemon Heart Gold and Soul Silver - Walkthrough - Celadon City Pokemon Heart Gold and Soul Silver: Walkthrough - Celadon City
Not as many things to do here as it may look. First, go to the Department Store, you can buy some TMs and other useful items that are not avaliable in Goldenrod City. On the second floor, talk to CRASHER WAKE, who is standing in the top right. He will give you the TURTWIG MASK, CHIMCHAR MASK, and the PIPLUP MASK. These are three accessories. Now exit the Department Store.

There is also a Game Corner. The Tips man is inside there, but he doesn't tip you on the Gym.

To get to the Gym, you will need a Pokemon that knows CUT. Once you have the Pokemon, go to the bottom right of the city, and CUT the cuttable tree that is there to access the path that leads to the Gym.

Enter the Gym!
