Sunflower's 151 — Bay Area's Largest Pokémon Cosplay Meetup

I built this site for Sunflower's 151, the largest cosplay photoshoot event of the year in the Bay Area — a fan-made Pokémon meetup where hundreds of people dress up as Pokémon.

The site lets everyone see which Pokémon are still available to cosplay. Data comes from Google Sheets, so organizers can update availability without touching code.

Unofficial fan project. Not affiliated with Nintendo or The Pokémon Company.

What I built

Landing page

Event info up front, with a clear call to join and links into the Pokémon lineup.

Pokémon still available

Lists every Pokémon still open to cosplay. Organizers flip the available value in the Google Sheet and the site updates automatically.

Who's That Pokémon?

Claimed Pokémon move here. The site matches each one to the cosplayer's Instagram handle so attendees can see who's taking on each character.

Powered by Google Sheets

Two sheets drive the app so organizers stay out of the codebase:

Sheet 1 — Pokémon availability

  • National Dex #
  • Pokémon name
  • available (TRUE / FALSE)
  • Image URL

Sheet 2 — Cosplayers

  • Pokémon name
  • Instagram handle
  • Signup information

The React app combines both sheets:

  1. Fetch the Pokémon availability sheet.
  2. Fetch the cosplayer sheet.
  3. TRUE Pokémon → show as available.
  4. FALSE Pokémon → move to Who's That Pokémon?
  5. Match claimed Pokémon with the cosplayer's Instagram handle.
  6. Ignore non-Pokémon signups (e.g. Nurse Joy or Team Rocket Grunts).

If someone claims Pikachu, the organizer only changes Pikachu from TRUE to FALSE in the spreadsheet. No code changes required.
