Pokemon Legends Arceus is set in a time before the rest of the games in the franchise. This means that the Pokedex isn’t as advanced and as such, you need to investigate Pokemon to learn more information about them. In this guide, we have listed all the Investigations in Pokemon Legends Arceus.
Pokemon Legends Arceus Investigations
Pokemon games are all about catching new Pokemon, raising them, and pitting them against other Pokemon in battles.
However, there’s more to a Pokemon game than that. Every new Pokemon that you run into needs to be investigated to have more information about it. Pokedex wasn’t always this intelligent!
Given that Pokemon Legends Arceus is supposed to represent a time before all of the remaining Pokemon games, it has a lot of investigations that are pending.
You’ll be doing investigations either before or after catching certain new species of Pokemon in Pokemon Legends Arceus.
Investigation #1 – The Bidoof Bothering the Village
Pokedex is unaware of Bidoof, but that doesn’t mean Bidoof is a rare Pokemon. There’re abundant of them in Pokemon Legends Arceus.
You’ll find them roaming around the Obsidian Fieldlands quite early on in the game. Catching one of them will unlock the Bothersome Bidoof request.
Next, head over to the Galaxy Hall in the village to begin this request. Complete the request to complete this challenge.
As a part of the request, you’ll be locating and capturing three Bidoof. One of them could be found near your home.
There’s another one roaming around at the far side of the village pasture.
The last one is next to a building that is under construction. Look for it behind the fence.
Investigation #2 – What Would Make Blissey Help a Human
Capturing Blissey will unlock the A Bit of Help from Blissey request. However, the request cannot be completed until you’ve unlocked Alabaster Icelands.

In the meantime, you’ll be required to catch a Silicon and a Cascoon. Once they’ve been caught, you’ll have to talk to the guard again and catch another Wurmple. Next, the Wurmples Evolved request will be unlocked.
