All About the Pokémon GO Event: Party Hat and Flower Crown Costume Pokémon

Costume Pokémon are some of the most exciting and collectible features in Pokémon GO, and Party Hat and Flower Crown variants sit at the top of many trainers’ wish lists. 

These special Pokémon appear only during limited-time events, wearing themed headgear that reflects celebrations, seasons, or festivals. 

Beyond their charming appearance, they often include shiny possibilities and evolvable forms, making them highly desirable for collectors and long-term players alike.

What is Party Hat and Flower Crown Costume Pokémon in Pokémon GO?

Party Hat and Flower Crown Costume Pokémon are special versions of existing Pokémon that wear unique head accessories during specific Pokémon GO events. 

While they retain the same base stats and moves as their regular counterparts, their visual designs make them exclusive collectibles.

These costume Pokémon are usually tied to celebrations such as anniversaries, holidays, or seasonal festivals. Importantly, many of them can be evolved, keeping the costume through evolution, which adds extra value for trainers aiming to complete full evolutionary lines.

Niantic uses costume Pokémon to encourage event participation, exploration, and trading, especially for trainers who enjoy completing Pokédex variations rather than focusing solely on battle performance.

Party Hat Pokémon: Origins, Variants, and Evolutions

Party Hat Pokémon first appeared in Pokémon GO during Pokémon Day 2018, marking the franchise’s anniversary. The most iconic of these is Party Hat Pikachu, typically wearing a colourful or purple party hat. Soon after, Party Hat Pichu was introduced through eggs, giving players an incentive to hatch during event periods.

Party Hat Pokémon usually spawn in the wild, appear in eggs, or feature in limited research tasks during celebrations such as New Year, Pokémon GO anniversaries, or milestone events. One of their biggest attractions is the availability of shiny versions, which are significantly rarer and highly prized by collectors.

From an evolution standpoint, most Party Hat Pokémon evolve using standard candy requirements. For example, Party Hat Pichu evolves into Party Hat Pikachu, and in some events, Pikachu can further evolve while retaining its festive headwear. This continuity makes them especially appealing for players who enjoy building themed Pokémon collections.

Flower Crown Pokémon: Seasonal Style and Collector Appeal

Flower Crown Costume Pokémon were introduced later, gaining popularity during spring-themed events around 2020. 

These Pokémon wear floral headpieces inspired by real-world seasonal celebrations, such as cherry blossom festivals and spring holidays.

Notable Flower Crown Pokémon include Pikachu, Eevee, Buneary, and their respective evolutions. Flower Crown Eevee is particularly sought after because it can evolve into various Eeveelutions like Vaporeon, Jolteon, and Espeon, all while keeping the floral crown.

These Pokémon appear through different methods depending on the event: wild spawns, raids, field research tasks, or special event encounters. Like Party Hat Pokémon, many Flower Crown variants also have shiny forms, adding another layer of rarity.

For collectors, Flower Crown Pokémon represent elegance and exclusivity, especially when complete evolutionary families are available during limited event windows.

Event Appearances and Availability

Party Hat and Flower Crown Costume Pokémon are closely linked to Pokémon GO’s seasonal and thematic events. These include annual celebrations, Community Days, and limited-time festivals such as Spring into Spring.

Recent examples include cherry blossom-themed Flower Crown Pokémon appearing in 2023, which attracted strong engagement from the community. However, as of December 2025, there is no active event featuring Party Hat or Flower Crown Pokémon.

Niantic frequently rotates costume Pokémon, meaning older variants often return unexpectedly. Trainers should regularly check in-game news, official social media channels, and event announcements to avoid missing future appearances.
