If you’re looking to add the mythical Celebi to your Pokémon Go collection, you need to complete the A Ripple in Time Special Research tasks, which were added to the game back in 2018.
There are 22 tasks to complete across eight sections, and we’ve listed all of them below, along with their respective rewards, so you can plan ahead by knowing what Pokémon Go expects of you. We’ve included some tips on how to complete certain tasks as well, but a lot of them will simply require a lot of time and patience.
As a dual Psychic and Grass type, Celebi is naturally a good counter against Water and Fighting types, particularly with its Psychic and Magical Leaf attacks. However, it’s not considered an optimal choice for PvP or PvE battles due to its low damage output and lack of moveset versatility. You get Celebi more for completion’s sake than anything else.
Pokémon Go: A Ripple in Time tasks and rewards
Part 1
The first set of tasks are:
- Power up a Pokémon 5 times—Requires Stardust and Candy, which can be acquired simply by catching Pokémon or hatching Eggs
- Battle in a Gym 2 times—This only applies to regular Gym battles, not Raids. Also, you don’t need to worry about winning; just battling in a Gym is enough
- Battle in a Raid
Your rewards for completing these tasks are 10 Poké Balls, a Fast TM, and a Super Incubator for hatching Eggs.
Part 2
The second set of tasks are:
- Make 3 new friends—If you don’t know enough people to complete this one, there is a dedicated subreddit and website where other players will happily share their Friend Codes
- Evolve an evolved Grass type Pokémon—This refers to Pokémon that have evolved once already, such as Ivysaur and Bayleef
- Catch a Pokémon 3 days in a row
Your rewards for completing these tasks are 1,500 Stardust, a Sun Stone (which you’ll need for the next set of tasks), and a Premium Raid Pass.
Part 3
The third set of tasks are:
- Reach level 25—You will earn player experience just by playing the game and completing these tasks, but you can use Lucky Eggs to double the amount of experience you earn for 30 minutes. You can buy a Lucky Egg from the in-game Shop for 80 PokéCoins or a bundle of eight for 500 PokéCoins
- Use a Sun Stone to evolve Gloom or Sunkern—Both of these Pokémon can be found in grassy areas, especially in sunny weather
- Hatch 9 Eggs—Use the Super Incubator you got from Part 1 to help expedite this. You can purchase more Super Incubators from the Shop for 200 PokéCoins each
Your rewards for completing these tasks are an Eevee encounter (be sure to capture it since you’ll need for the next part), a King’s Rock, and a Premium Raid Pass.
Part 4
The fourth set of tasks are:
- Walk 10km with Eevee as your buddy to earn Candy—This will also contribute to evolving Eevee into Espeon
- Evolve Eevee into Espeon during the day—After completing the previous task, Eevee must be given 25 Candy during daytime to evolve into Espeon. Make sure it’s still your buddy before you evolve it, otherwise it won’t turn into Espeon. If you’ve never acquired an Espeon before, you can nickname your Eevee “Sakura” to trigger the evolution
- Send 20 Gifts to Friends
Your rewards for completing these tasks are another Eevee encounter (again, keep this Eevee for the next section), 2,500 Stardust, and a Metal Coat.
Part 5
The fifth set of tasks are:
- Walk 10km with Eevee as your buddy to earn Candy—Yes, you have to do this again, but you need to anyway for evolving Eevee into Umbreon
- Evolve Eevee into Umbreon at night—Just like with Espeon, you need to give Eevee 25 Candy and evolve it at nighttime while it’s your buddy. You can nickname it “Tamao” to instantly trigger the Umbreon evolution, but this only works if you’ve never acquired an Umbreon
- Trade a Pokémon—Trading costs Stardust, so stick with trading a regular Pokémon for one you already own since this trade is the cheapest. You can only trade with a player who’s within 100 meters of your location, so you’ll need to find a local group if you don’t know anyone else who plays Pokémon Go
Your rewards for completing these tasks are a Star Piece (which awards 50% more Stardust for 30 minutes), 15 Pinap Berries (which, when fed to wild Pokémon, double the amount of Candy they drop when captured), and an Up-Grade.
Part 6
The sixth set of tasks are:
- Visit PokéStops 7 days in a row
- Use 25 Pinap Berries while catching Pokémon—Aside from the ones you earn from completing Part 6, you can acquire Pinap Berries from PokéStops and Gyms
- Use items to evolve Pokémon 2 times—The King’s Rock, Metal Coat, and Up-Grade items you’ve earned so far can be used to complete this task, but any item-based evolution will count
Your rewards for completing these tasks are 3,500 Stardust, a Dragon Scale, and 5 Silver Pinap Berries (which, when fed to a wild Pokémon, increases the odds of catching it and how much Candy it drops).
Part 7
The seventh set of tasks are:
- Catch 40 Grass or Psychic type Pokémon—Grass types can be found in any grassy areas. Psychic types can be harder to find, but can show up in grassy and urban areas. Exeggcute and Exeggutor are dual Grass/Psychic so catching these will help
- Make an Excellent Curveball Throw—If you’re struggling, there are guides on YouTube to show how it’s done
- Earn a Gold Johto Medal—This is earned by catching 70 Pokémon from the Johto region AKA ones that debuted in Pokémon Gold & Silver. Examples include Chikorita, Cyndaquil, and Totodile
Your rewards for completing these tasks are a Charged TM, 10 Silver Pinap Berries, and an encounter with Celebi.
Part 8
At this stage, Celebi will appear, and you can capture it. Celebi will teleport, so you’ll need to constantly turn your camera to look for it, but you’ll be granted an unlimited amount of Poké Balls for this and there’s no time limit. Just keep throwing Poké Balls at it and, once you’ve hit it three times, it’ll be yours. You’ll also be rewarded with 5,500 Stardust, a Super Incubator, and 20 Celebi Candy.
