Tips

• This is one of the few places to catch a wild Mr. Mime, at levels 28 to 30 at any time of day.
• Tangela is the most common Pokémon in the grass, at levels 20 to 35.
• Surfing gives Tentacool and Tentacruel, while the Super Rod can hook Chinchou, Lanturn and Shellder.
• Swimmer Nikki's team is three Seel and a Dewgong, so Electric and Fighting moves work well.
• Use this route to get to Cinnabar Island and then Route 20, which unblocks Route 19.
