Pokémon Go event Pokémon list: All costume Pokémon, including party hat Pokémon, flower crown Pokémon and every Pikachu costume explained

Everything you need to know about the special costume Pokémon in Pokemon Go. 

Event costume Pokémon in Pokémon Go are special versions of certain Pokémon, which can be caught wearing a costume. This can be anything from a party hat to a deerstalker to what we're meant to believe is a flower crown.

Event costume Pokémon are released as part of an in-game event, such as a Community Day or a tie in event for a holiday like Halloween.

Each event costume Pokémon is very collectable, especially since there are, like regular Pokémon, shiny versions of these special Pokémon.

Raichu event costumes in Pokémon Go

Just like Pikachu, there is a range of costume Raichu for you to collect in Pokémon Go.

You can't find these Raichu out in the wild though. Instead, you'll need to evolve one of your costumed Pikachu. This means it's always a good idea to catch at least of each costumed Pikachu if you plan on becoming a costume collector.

It costs 50 Pikachu candies to evolve a Pikachu into a Raichu.

Only Straw Hat, Party Hat (Red) and Mimikyu Pikachu are unable to evolve into Raichu.

Below you'll find all the information you need about the various costumed Raichu's in Pokémon Go:

Pichu event costumes in Pokémon Go

There is a good selection of costumed Pichus for you to collect in Pokémon Go.

Costumed Pichu can only be found in eggs that are collected during the event period they're connected to. This means that, if you hold onto one of these eggs, it's possible that you might hatch a Pichu outside of an event.

Typically Pichu can be found in 7km, but it's always a good idea to check the specifics of the event just in case they're appearing in additional egg pools. This will make your task of tracking down that special Pichu a lot easier.

Here are all the costumed Pichu's that are currently available:

CostumeFirst Appearance
Santa Hat Holiday 2016 Event (12th December to January 2017) - 5km eggs

Flower Crown Pokémon in Pokémon Go

Flower crowns in Pokémon Go are not flower crowns, they are flower hair clips; crowns encircle a head, not hoover awkwardly above the right eye. Notably, it's possible to evolve a flower crown Eeevee, which, if you're not using an eeveelution trick, will result in a random flower crown eeveelution.

The easiest way to ensure you get the eeveelution you desire is to use the Eevee evolution name trick. This, however, only works once, so, if you've already used it to add that specific eeveelution to your Pokédex, then you need to try another method.

If you're aiming for either an Espeon or Umbreon, then you'll need to walk with the Eevee you wish to evolve as your buddy for 10km. Once you've done this, evolving this specific Eevee during the day will reward you with an Espeon or, at night, an Umbreon.

For a Leafeon or Glaceon, it's time to use those special lures at your nearest PokéStop. Placing a Mossy Lure Module will allow you to evolve the Eevee into a Leafeon, while a Glacial Lure Module will transform it into a Glaceon.

Here are all the Pokémon in Pokémon Go that currently wear a flower crown:

Kanto starters event costumes in Pokémon Go

Bulbasaur, Charmander and Squirtle - the Kanto, and most well known, starter Pokémon in the franchise. Thanks to this special status, the Gen 1 starters have been given a number of special costumes in Pokémon Go.

For Squirtle this includes a pair of sunglasses, which is reference to the Squirtle Squad from the Pokémon anime.

The clone versions of the final evolutions for the Gen 1 starters - Venusaur, Charizard and Blastoise - are a reference to Pokemon: The First Movie: Mewtwo Strikes Back, in which these three Pokémon, among others, are cloned by Mewtwo.
