The easiest place to find Horsea is in the Grand Underground, where several caves offer the chance to pick up the elusive creature.

There are a few places to find Horsea in Brilliant Diamond & Shining Pearl but all of them require you to have completed the Sinnoh Pokedex.

If you’ve cleared that benchmark you can find the Horsea on the waters of the Grand Underground at Fountainspring Cave, Riverbank Cave, and Still-Water Cavern.

After catching Horsea, you can optionally level it up to Lvl. 32 in order to evolve it into Seadra.

How to get Kingdra in Brilliant Diamond & Shining Pearl

Kingdra has a convoluted evolution process and requires you to pick up a special item along the way.

Kingdra is only attainable through evolution and the process to get there is a little complicated and requires the Dragon Scale item.

This special pickup can be collected from a Horsea, Seadra, Dratini, or Dragonair, but all of them have a very low percentage of carrying it.

When you do find one, you’ll either need to capture the Pokemon and give its item to the Seadra you want to evolve, or you could use Thief to steal it away without capturing.

After you’ve collected the Dragon Scale, you’ll still have to trade the equipped Seadra to someone you trust to trigger the evolution. Once that’s done simply trade back for your new Kingdra and celebrate the end of that long road.


That’s all you need to know about Horsea, Seadra, and Kingdra in Pokemon Brilliant Diamond & Shining Pearl.
