A new series of Special Research tasks have been added to Pokémon Go, this time offering Trainers the opportunity to catch the Mythical Pokémon Celebi, originally introduced in 2000’s Pokémon Gold and Silver. Celebi was revealed during Pokémon Go Fest 2018 and was made available to Trainers participating in the event. Now all Trainers everywhere will have a shot to get their own time traveling Celebi by completing all-new Special Research tasks.

Celebi is a Psychic / Grass type Pokémon and, as with all Mythical Pokémon, you’ll be able to catch only one. Celebi cannot be traded. And while Shiny Celebi’s model can be found in the game’s files, it’s unlikely that it is currently available.

If you haven’t already caught Mew, don’t worry. Mew’s Special Research is still available, and you can start completing the Celebi Special Research tasks once you reach stage 3 of the Mew tasks. This means you can work towards both earning Pokémon simultaneously!

As with the previous Special Research, in which Trainers could catch the Legendary Pokémon Mew, Professor Willow has a new set of tasks for Trainers to complete. Starting with “A Ripple in Time,” Trainers will have to complete seven stages of tasks, with the eighth stage presumed to give players the opportunity to catch Celebi.

This time, tasks are centered around Pokémon from the Johto region, which now have increased spawn rates in the wild. You’re going to need them, too, as one of the tasks requires you to obtain a Gold Johto Medal, earned after registering 70 unique Johto region Pokémon in your Pokedex.

Completing tasks will not only progress towards catching Celebi, but will also reward experience and items, including an all new berry: Silver Pinap Berry. This berry can be used on a wild Pokémon to make the it easier to catch (1.8x) and also increases the amount of candy rewarded for catching it (2x). You’ll also be able to receive a handful of evolution items as rewards, which you’ll need to complete a task in stage six.

Most of the required Special Research tasks range are easy, like the one requiring you to catch a Pokémon three days in a row. There are few more challenging tasks, two separate tasks in particular, across different stages, which require you to evolve Eevees into both Espeon and Umbreon. You can learn how to obtain those Pokémon with the help of this guide. Thankfully, in case you missed the recent Community Day, you’ll be granted Eevee encounters for completing the stages prior to those requiring this evolution.

Trainers over at r/TheSilphRoad are hard at work completing these tasks, progressing toward an encounter with the Mythical Pokémon. Here’s what you’ll have to do to catch Celebi in Pokémon Go:
