Wiglett was suddenly dropped into Pokémon Go on April 22 to coincide with the new Biome update, which updates the backdrops when catching Pokémon to make things feel more colorful and alive.

Wiglett was meant to be an exclusive spawn to the Ocean Biome. It could only be found by going to beaches or areas with water and sand, making a holiday getaway alluring for Pokémon Go players looking to catch ’em all. That was, until some eagle-eyed trainers found Wiglett in places where it shouldn’t have been appearing.
