it depends on the system
Use a good rod where you can find horsea use your pokedex if you seen one already.
in whirl islands you have to have surf
Nobody knows lol.
You can find Horsea around Whirl Islands, and I suppose you can evolve it from there.
You can catch it on route 133 and 134 with a rod.
Simple find a good rod from a fishing guru and go to the shore of island 6 and use it until you get horsea. -PokemonAnswerMaster-
Horsea is a Kanto region pokemon.
