Horsea (Japanese: タッツー Tattu) is a Water-type Pokémon. It evolves into Seadra starting at level 32, which evolves into Kingdra when traded holding a Dragon Scale.
Horsea is a small, light blue seahorse with tiny scales. It has no arms or legs, only a single fin on its back and a tightly curled tail. Its belly and fin are cream colored, and it has red eyes. There are three spike-like projections on either side of its head. The single fin on its back is used for locomotion in the water.
