Wigglets made their debut as part of Pokémon Go’s biome update. For those looking for a special Pokemon that is not a regional form of Diglett, but a Pokemon in its own right, they have come to the right place.
Wigglets spawn in beach biomes, but it’s a bit unclear to understand what counts as a beach biome. Players on Reddit are reporting that Wigglets also spawn near lakes. This means that Wigglets are likely to only spawn near bodies of water. Since these biomes are so new, it’s a little hard to tell if this is 100% intentional or if all bodies of water are considered “beach” biomes. We will update this guide as more information becomes available.
For now, your best bet is to check the radar as you approach a body of water to see if Wigglets are nearby. Its long silhouette is unmistakable, so you should be able to spot it easily among all the other invisible Pokémon. You should also be sure to pay attention to whether the area where you will be staying near the water has a beach biome aesthetic.
Wiglet originally debuted in Pokémon Scarlet and Purple as what people thought was a regional variant of Diglett, but it turns out that Wiglet itself is not a wonder of evolution, but something unique in its own right. It soon became clear.
