The Mysterious Will-o'-the-Wisp is a Request in Pokémon Legends: Arceus.
A villager named Paira wants you to catch the will-o'-the-wisp she saw on Windswept Run to prove to Waka that she's telling the truth. It turns out the will-o'-the-wisp was a Chimchar all along! Catch one so you can show it to Paira in the village at night, when its tail can be seen glowing in the dark.
