Piplup's evolution in Pokemon GO can be a powerful Pokemon to use, and since the community day, it's become one of the most powerful water-type Pokemon.
Since fans were able to catch Piplup during the community day on Sunday. Some were looking to farm shinies while others were farming perfect Piplup with powerful CP stats so they could evolve it into Empoleon.

At level 16, Piplup evolves into Prinplup, but the real strength happens at level 36 when Prinplup evolves into Empoleon. But what's the best moveset for Empoleon?
Piplup Evolution Pokemon GO: Best Moveset
Before the community day and the inclusion of a powerful move, players used Metal Claw and Hydro Pump as the best moveset. That changed to Metal Claw and Hydro Cannon.
Although, if you want to have a Empoleon that's strictly water based, use Waterfall and Hydro Cannon. He'll be a powerful water-type Pokemon which also has a Steel-type to help with some weaknesses.
