The latest Pokémon Go event, “Evolving Stars,” runs from Oct. 5-11 and features Pokémon who evolve using items and trades. The event features multiple Collection Challenges, special Field Research, and special spawns.

Notably, the event also adds a few more tasks to the Cosmog Special Research, “A Cosmic Companion.”

Below, we list out all the “Evolving Stars” Collection Challenges, spawns, Field Research, and raid targets.

Evolving Stars Collection Challenges

Unless you’re going for Collection Challenge medals or you need the evolution item rewards below, these challenges are probably not worth the stress. It can serve as a nice reward if you don’t have some of these evolutions already, but I would not stress over evolving Eevee into the correct evolution just to get these items.

Eevee’s three evolutions — Vaporeon, Jolteon, and Flareon — are completely random, assuming that you’ve used the naming trick to get each one guaranteed once.
