Arrokuda and Barraskewda are the Gen 8 fish pair added to Pokémon Go for the Ultra Unlock: Water Festival event, which runs from 10AM on August 18th to 8PM on August 24th, 2026, local time. Arrokuda is not a wild spawn during the event, so bumping into one while walking around is not going to happen. You have to go get it from one of three specific places.
Quick answer: Catch Arrokuda from a Rainy Lure Module, the event Field Research task “Catch 15 Water-type Pokémon,” or Go Pass: Water Festival ranks 13 and 28, then spend 50 Arrokuda Candy to evolve it into Barraskewda.
Where to find Arrokuda in Pokémon Go
All three sources are tied to the event window. Once the Water Festival ends, none of them are guaranteed to stick around, which is the main reason to grab at least one Arrokuda before August 24th.
| Source | What you need to know |
|---|---|
| Rainy Lure Module | Arrokuda is attracted to Rainy Lures more often during event hours |
| Event Field Research | Task: Catch 15 Water-type Pokémon. Reward is Arrokuda, Feebas or Clamperl |
| Go Pass: Water Festival | Encounters on the free and Deluxe tracks at rank 13 and rank 28 |
Use a Rainy Lure Module for repeat Arrokuda encounters
This is the only method that can hand you multiple Arrokuda back to back, which makes it the fastest path to 50 candy. A Rainy Lure Module also shows up as a free Go Pass reward, so you may not need to buy one.
Field Research task: Catch 15 Water-type Pokémon
The event-exclusive research task rewards an encounter, but not always the one you want. Arrokuda shares the reward slot with Feebas and Clamperl, so a single completion is a coin flip and you will probably need several.
Which PokéStops hand out which tasks is decided per Stop and reshuffles daily, so spinning the same three Stops near your house may never produce it. Local Pokémon Go communities usually map out the good Stops within a few hours of a reset, and that saves a lot of pointless walking.
Note: the task disappears when the event ends on August 24th, along with the Arrokuda reward attached to it.
Go Pass: Water Festival encounters at ranks 13 and 28
Every trainer gets the free Go Pass: Water Festival automatically, and Arrokuda encounters sit at rank 13 and rank 28 on it. Paying for the Deluxe track adds encounters at the same two ranks, so a Deluxe holder who reaches rank 28 walks away with four guaranteed Arrokuda.
Two other Go Pass ranks are worth chasing first. Rank 10 switches on 2× Catch Candy and rank 20 halves egg hatch distance, and both bonuses stay active for the rest of the event once unlocked. Hitting rank 10 before you start Lure hunting stacks with Pinap Berries.
How to evolve Arrokuda into Barraskewda
Barraskewda costs 50 Arrokuda Candy and nothing else. There is no item, no buddy walking requirement, no trade condition, and no time-of-day gate, which means catching Arrokuda is the entire difficulty.
If the Evolve button is greyed out, the only cause is candy. Arrokuda Candy is not shared with any other family, so Water-type candy from Feebas or Clamperl catches will not help.
Fastest ways to reach 50 Arrokuda Candy
A normal catch gives 3 candy, and a Pinap Berry doubles that. With the rank 10 Go Pass bonus running, a Lure session that produces a handful of Arrokuda can realistically finish the job in one sitting.
Setting Arrokuda as your buddy is the slow backup. It earns candy every 3 km walked, which is fine if you only ever get one encounter and want to bank progress after the event ends.
Barraskewda stats, weaknesses and moves
Barraskewda is a pure Water type built almost entirely around attack, with defense and stamina trailing well behind. That glass cannon shape shows up in Great League too, where the best IV spread is a low-attack 0/14/14.
| Detail | Value |
|---|---|
| Pokédex number | #847, Water |
| Attack / Defense / Stamina | 258 / 127 / 156 |
| Max CP (level 50) | 3,003 |
| Weak to | Electric, Grass (160%) |
| Resists | Fire, Water, Ice, Steel (62.5%) |
| Buddy distance | 3 km |
| Second charged move | 50,000 Stardust and 50 Candy |
Its move pool is small. Waterfall paired with Crunch is the strongest raid combo, while Aqua Jet is the cheapest charged move to fire off in Trainer Battles.
| Move | Type | Category |
|---|---|---|
| Waterfall | Water | Fast |
| Bite | Dark | Fast |
| Peck | Flying | Fast |
| Aqua Jet | Water | Charged |
| Crunch | Dark | Charged |
| Close Combat | Fighting | Charged |
Shiny Arrokuda and shiny Barraskewda are not available
Neither form is shiny in Pokémon Go at debut, which is standard for new additions. Shiny releases usually arrive at a later event, and a future Water Festival is the obvious candidate, though nothing has been confirmed.
The shiny palette itself is a modest change. The brown scaling turns a metallic light blue with grey shading in places, and the difference is easy to miss at a glance.
The practical takeaway is to secure one Arrokuda before 8PM on August 24th even if you cannot reach 50 candy in time. Arrokuda has no confirmed availability after the Water Festival, and holding a single one lets you walk it as a buddy and finish Barraskewda whenever the candy catches up.
