Snowpoint City is the home to the seventh gym leader, Candice.

Tasks

• Someone in the left-hand side house will gladly trade you her Haunter for a Medicham.
• The man in the right-hand side house will tell you a trendy saying every day. That word will be added to the game's vocabulary system.
• Once you have become the League Champ and have gained the National Dex, return to Snowpoint to gain entrance to the Snowpoint Temple. Deep within the confines of the temple you will find Regigigas, who will only fight if you have Regirock, Regice, and Registeel in your party.
