Niantic and The Pokémon Company International today revealed Pokémon GO’s next in-game celebration, the Pokémon GO Water Festival.

From today at 4:00 PM EST until March 29th at 4:00 PM EST, trainers will be more likely to encounter Water-type Pokémon like Magikarp, Squirtle, Totodile and their evolutions around the world. Trainers will also have a greater chance of encountering Water-type Pokémon originally discovered in the Johto region, which recently began appearing in the game, when exploring areas where Water-type Pokémon more commonly appear.

To coincide with the festivities, beginning today trainers will also have access to a new avatar wardrobe item, the Magikarp Hat.
