1. Catch a Slowpoke: Slowpoke can be found in the following locations:
* Route 207: After obtaining the National Pokédex from Professor Rowan.
* Route 212: After obtaining the National Pokédex from Professor Rowan.
* Route 213: After obtaining the National Pokédex from Professor Rowan.
* Grand Underground: While digging in the Grand Underground.
2. Obtain a King's Rock: This item is needed for Slowpoke to evolve into Slowbro. You can obtain it from:
* A Trainer: You can obtain a King's Rock from the Trainer near the entrance of the Great Marsh.
* Grand Underground: You can find it while digging in the Grand Underground.
* Trade: If you can't find one, you can always trade for it with another player.
3. Evolve Slowpoke: Once you have the King's Rock, simply trade it to your Slowpoke. Slowpoke will then evolve into Slowbro!
Note: There is another way to evolve Slowpoke into Slowbro, but it requires Pokémon Pearl or Platinum:
* Trade Slowpoke with a Shellder: Trade your Slowpoke with a Shellder in Pokémon Pearl or Platinum. Slowpoke will automatically evolve into Slowbro upon trading.
Enjoy your newly evolved Slowbro!
