Celebi has finally made an appearance in Pokémon GO, and joins Mew as one of only two Mythical Pokémon in the game to date. Much like Mew, you also unlock Celebi through a lengthy Special Research Quest.

It's called A Ripple In Time, and it acts very similarly to A Mythical Discovery. You have to perform a series of objectives that cover pretty much all aspects of Pokémon GO, earning rewards each step of the way.

In this guide, we're going to walk you through this Special Research Quest to help you unlock Celebi much faster.

How To Catch Celebi In Pokémon GO

Before we get started, let's take a look at how catching Celebi works. Just like with catching Mew, you have to complete a Special Research Quest. This is a series of eight objectives you have to beat to get a chance at catching Celebi, and you'll earn rewards by completing each step along the way.

These differ from Field Research Quests in that they're fixed, and you have to complete them in a specific order. That does mean that you can plan ahead though, and prepare what you might need to whiz through objectives you unlock later.

The one area that A Ripple In Time differs from A Mythical Discovery though, is that there's an unlock requirement. You first have to reach the third objective of A Mythical Discovery, the Special Research Task you have to beat to unlock Mew.

We'll now run through every single stage in A Ripple In Time to help you plan ahead.
