There are quite a few Pokemon in Arceus that have unique investigation challenges as part of their Pokedex. These are optional but they are usually an easy way to get enough points to fill the Pokedex for that Pokemon. As with all of these missions, you will first need to catch a Croagunk before this Investigation can be solved as it’s tied to Request #34 – Croagunks Curative Poison. Once you have the Request, you can complete the investigation.
Investigate Croagunk Poison’s Medicinal Properties In Pokemon Legends Arceus
This investigation becomes available once you have caught a Croagunk. Once you have caught one and progressed far enough into the story, you will find a Request for it on the board in the professors lab. Collecting the Request has the nurse ask you to deliver a Croagunk. So all you need to do is give her the Croagunk you’ve already caught and you’ll be able to complete the Request.
Completing the Request completes the investigation.
