In the Pokemon Emerald version of the popular video game series, players must obtain a special move called “Waterfall” to progress through certain areas. HM Waterfall allows the player’s Pokemon to travel across bodies of water, opening up new areas to explore and new challenges to overcome.
To obtain HM Waterfall in Pokemon Emerald, the player must first defeat the Sootopolis City Gym Leader, Wallace. After defeating Wallace, the player will receive the Rain Badge, which will allow them to use the move Waterfall outside of battle. The player can then find HM Waterfall in the Granite Cave on Route 116.
