Petrdex is a community-driven digital Pokédex-style catalog dedicated to the legendary world of Petrs — the students who create and distribute the beloved Petr stickers you see across campus. Each Petr and sticker has its own entry, complete with sightings, variations, lore, and creator info (when known 👀).

Whether you're a collector, a trader, or simply a fan of the culture, Petrdex helps you:

Discover rare, seasonal, and iconic Petr stickers. Track your personal sticker collection. Learn about the artists and the stories behind each Petr. Celebrate the creativity that makes UCI's community so uniquely chaotic and wholesome. Petrdex isn't just a database — it's a living record of campus culture.

Catch them. Collect them. Cherish them.
