Poliwag is a water-type pokemon that can be found to the left of Viridian City during the night. It evolves into a Poliwhirl at level 25, and then you have the choice to either expose it to a Water Stone to evolve it into a Poliwrath which is a water/fighting type or trade it while it holds a King's Stone to evolve it into a Politoed.
== Pokedex ==
The Direction of the spiral on the belly differs by area. It is more adept at swimming than walking.
