In October 2026, a creator known as 999999999 released a fan game called Pokémon Oops! All Eevees that modifies the classic Pokémon FireRed title. The game replaces all standard monsters with 326 custom Eeveelutions, drastically expanding upon the eight official evolutions.
Why it matters
The project serves as a massive fan-made expansion for a series that has not introduced a new official Eeveelution in 13 years. By utilizing the FireRed engine, the game provides a nostalgic yet entirely fresh experience for series enthusiasts.
The game features 326 new Eeveelutions across the 18 standard Pokémon types, including unique additions like Fanteon and Aeraerieon. A promotional video showcasing every creature has a runtime of 40 minutes.

The developer modified the base Pokémon FireRed game to replace all monsters with custom designs and added trainer outfits inspired by the Eeveelution theme. Players can even trigger a feature that allows them to evolve the player character itself.
Timeline
2013: Game Freak introduced the last official Eevee monster.
October 2026: The fan game was released to the public.
November 21, 2026: The developer plans a game update.
Culture Shift
The project represents a growing trend of ROM hacking where developers use the Pokémon FireRed game base to build expansive, non-official sequels. This movement challenges traditional content release cycles by filling gaps left by official studio development.
Fans can access the modification by downloading the files directly from the PokéCommunity forums. Because it is a mod of the original title, users will need their own base game assets to play.
The takeaway
This fan project demonstrates the enduring popularity of specific creature designs despite long periods without official new additions. Players looking to try this should ensure they have the proper base files to avoid technical issues.
What happens next
The developer has announced plans to release a game update on November 21, 2026.
