It is understandable why Pokémon Go fans are upset after the new snake went extinct in many countries following a recent update from developer Niantic. After making its debut during the game's latest Sustainability Week event, the sand snake Pokémon, Silicobra, has vanished from much of the globe due to sudden changes in spawn criteria.

Players originally began tracking Silicobra using maps derived from US government geographical data. However, just hours after these maps were widely shared, Niantic altered its spawning logic. While the developer initially declined to comment on specific appearance rates, they later addressed the situation on X/Twitter, stating: "Trainers, we've adjusted Silicobra encounters to align more closely with its natural habitat. You can now find Silicobra slightly more frequently in desert-like areas."

Why Pokémon Go Fans Are Upset After New Snake Goes Extinct in Many Countries

The recent adjustment has led to a massive reduction in availability across several major regions. According to the most recent community-made maps, Silicobra is now effectively "extinct" in the following areas:

  • The Eastern United States
  • Most of Europe
    • (For UK players, the nearest spawn point is likely Marseille, France)
  • Japan

The sudden rollback has caused significant frustration within the community. On the TheSilphRoad subreddit, user mal138 expressed disappointment over the change, noting that while they enjoy new regional Pokémon, the rollback was frustrating.

User Study_Realistic described the situation as a "rug pull," explaining that the difficulty of finding a rare Pokémon is part of the fun, but moving the goalposts ruins the experience. They noted that unlike Wiglett, which can be found at predictable beach locations, Silicobra was virtually unavailable in the UK unless players were in a highly specific spot on a Tuesday.

The Need for Transparency and Biome Indicators

The lack of clear communication regarding these changes has turned exploration into a "blind guessing game." User k6nch6n argued that when Niantic implements "fixes" behind the scenes without notice, it undermines the real-world efforts players make to visit specific habitats.

Many players are now calling for an in-game biome indicator to help identify suitable areas. Currently, players must rely on third-party tools because there is no way to easily determine where a "desert" area begins. This issue is compounded by the lack of visual cues; user Mix_Safe pointed out that there is no distinct "desert" background shift in the game to assist with identification.

The frustration is heightened by the fact that Silicobra was not available through any alternative methods, such as eggs, field research, or even a premium event pass. Without these secondary options, players are left entirely dependent on unpredictable spawns in specific geographic locations.
