Yellow Horsea Best Moveset

Best Build

Gen 1 build content has limited support (no abilities, held items, or natures).

Try selecting a different game/generation filter, or check back later.

Moves

Most of Horsea's flexibility comes from TMs. Same-type output runs through Hydro Pump and Surf, but Normal and Ice and the rest of the TM pool push it from predictable to genuinely threatening.
