Pokémon Go’s yearly “Sustainability Week” event has kicked off for 2026, running from April 14-20. This event features the debut of Silicobra, the snake Pokémon from Galar, as well as a special costumed Galarian Corsola with cute pink sunglasses and shiny Toedscool.
Below we list all the bonuses for Pokémon Go‘s “Sustainability Week” 2026 event, including what’s featured in the Go Pass, boosted spawns, and egg hatches. We also explain where to find a Silicobra during this event.
How to find Silicobra in Pokémon Go
Silicobra makes its debut with this event, but it’s not locked behind anything in particular. You can only find Silicobra in the wild, as of writing this. The blog for the event notes that it’s in “desert-like areas” and players have noted that it’s pretty hard to find. Players are also saying that it seems like Silicobra can be found around sand in general, with one report saying that they were found on golf courses (which have sandpits).
It’s not a reward from Field Research, the Go Pass, nor from eggs or raids, so you’ll need to get pretty lucky or travel to somewhere sandy to find one.
As a reminder, Silicobra evolves into Sandaconda using 50 Silicobra Candy, but note that Sandaconda does have a Gigantamax form, so you may want to save your candy for when that inevitably debuts.
Pokémon Go ‘Sustainability Week’ 2026 event Go Pass bonuses
As usual with events nowadays, this event has its own battle pass, Go Pass: Sustainability Week. Notably, you’ll get a Galarian Corsola (sunglasses) at ranks 19 and 30, both on the basic and the paid version of the pass.
At rank 10, you’ll get a bonus of doubled XP from spinning PokéStops. This bonus is tripled if you buy the deluxe pass. At rank 20, you’ll unlock halved hatch distance for eggs and this bonus is for both the basic and deluxe pass.
Additionally, if you like collecting poses, there’s a “Potted Plant pose” unlockable at rank 15, but only if you upgrade to the deluxe pass.
