When is Pokémon Go’s Sustainability Week 2023 event?
Niantic has confirmed that Sustainability Week 2023 will only happen for six days, starting on April 20, 2023, at 10 AM and ending on April 26, 2023, at 8 PM in your local area. During this time, several unique Pokémon will have increased spawning timers and multiple bonuses will be enabled.
Every new debut in Pokémon Go’s Sustainability Week 2023 event
There are three Pokémon making their debut in Pokémon Go during Sustainability Week 2023: Bounsweet, Steenee, and Tsareena. Steenee is the evolved form of Bounsweet, and Tsareena is the final form. You can evolve Bounsweet into Steenee by using 25 Bounsweet Candies, and Steenee will become Tsareena by using 100 Bounsweet Candies.
Outside of the new Pokémon, Drilbur will get its shiny form for the first time. It will have an increased chance to appear throughout the event and will remain available as a chance to appear to encounter a Drilbur in the wild, as a reward, or as a Raid encounter.
Can Bounsweet, Steenee, and Tsareena be Shiny?
Because these three Pokémon will debut in Pokémon Go, we can confirm that Bounsweet, Steenee, and Tsareena cannot be shiny. Nearly every Pokémon that arrives at the mobile game for the first time does not have their shiny version, but there have been exceptions to this rule before.
