We’ll break down boosted spawns, lucrative Field Research tasks, and potential egg hatches, ensuring you can maximize participation in an event that celebrates both conservation and exceptional gameplay opportunities.
How to Find and Capture Silicobra
Making its global debut is the ground-type serpent from Galar, Silicobra. Importantly, this new addition is not tied to raids, eggs, or research tasks; it is exclusively available as a wild spawn for the duration of the event. According to Niantic’s official notes, Silicobra is most likely to appear in “desert-like areas,” a detail corroborated by player reports indicating habitats involve sand. Initial community findings suggest locations such as golf courses with sandpits, beaches, and arid biomes offer the highest chances of an encounter. This targeted spawn mechanic encourages exploration of specific terrain. Evolving Silicobra into Sandaconda requires 50 candies, and astute trainers may consider stockpiling additional candy, as Sandaconda’s formidable Gigantamax form will likely arrive in a future update.
Go Pass: Sustainability Week Bonuses and Rewards
A central feature of the event is the tiered Go Pass: Sustainability Week, available in both a free Basic track and a premium Deluxe version. Both tracks offer the coveted costumed Galarian Corsola (wearing stylish pink sunglasses) as rank rewards at levels 19 and 30. Key bonuses activate at specific rank milestones. At rank 10, the Basic pass grants doubled XP from spinning PokéStops, a bonus that is tripled for Deluxe pass holders. Rank 20 provides a universally beneficial halved egg hatch distance. For collectors, the unique Potted Plant avatar pose is a compelling exclusive, unlockable at rank 15 but only for trainers who upgrade to the Deluxe pass.
Event Field Research Task List and Rewards
Spinning PokéStops during Sustainability Week 2026 yields special Field Research tasks with event-themed rewards. Completing these tasks is an efficient method for securing encounters with featured Pokémon and gathering valuable items. The available tasks are as follows:
- Catch 5 Pokémon (Reward: 10 Poké Balls or 3 Ultra Balls)
- Catch 10 Pokémon (Reward: Castform encounter)
- Catch 15 Pokémon (Reward: Combee or Cherubi encounter)
- Walk 3 km (Reward: Trubbish encounter)
- Hatch 2 Eggs (Reward: Galarian Corsola [sunglasses] encounter)
Boosted Wild Spawns and Route Encounters
The event significantly increases the appearance rate of several Pokémon in the wild. The officially confirmed boosted spawns include Seedot, the debutant Silicobra, Wiglett, Toedscool, and Castform, the latter of which has an increased chance of appearing in its shiny variant. Community reports have further noted elevated frequencies of Foongus, Binacle, Cutiefly, and Gossifleur. For trainers following Routes, special daily rotations offer additional encounter opportunities: Togetic (with boosted shiny odds) is featured from April 14-16, Trubbish (also with boosted shiny odds) from April 16-18, and Lapras (with boosted shiny odds) from April 18-20. Throughout the week, the costumed Galarian Corsola (sunglasses) will also spawn from Routes.
Event Egg Pool for 7 km Eggs
Eggs obtained from Gifts during the event period contain a curated pool of Pokémon when incubated. Any 7 km egg acquired between April 14 and 20 has the potential to hatch the following species: Lapras, Togepi, the costumed Galarian Corsola (sunglasses), Castform, or Trubbish. Notably, both Galarian Corsola (sunglasses) and Castform hatched from these event eggs carry an “increased chance” of being shiny, adding significant value to the egg-hatching mechanic, especially when combined with the halved hatch distance bonus from the Go Pass.
Sustainability Week 2026 successfully merges thematic environmental awareness with substantial gameplay incentives, offering a balanced mix of challenging hunting for the rare Silicobra, strategic progression via the Go Pass, and diverse methods for shiny hunting through wild spawns, research tasks, and eggs. This event structure encourages active exploration across varied habitats while providing clear pathways for trainers to expand their Pokédex with unique costumed variants and a highly anticipated new species from the Galar region.
