Pokemon Legends: Arceus — Request 44 Guide (The Pokemon in the Nighttime Photo)

gamerant.com:

Photos can be taken just about anywhere in Pokemon Legends: Arceus, but for those that want a traditional studio, they can find what they're looking for in Jubilife Village. At the start, the functions of the photography studio will be very limited, with minimal background and lens options to choose from. However, the more the player character helps the Galaxy Team, the more chances they'll get to improve Jubilife Village — including the studio.

Request 44 is part of a series of sidequests in Pokemon Legends: Arceus. As such, they're not required to complete, but they will be if players are going for 100% completion. Fortunately, they're not too challenging so long as players know what Pokemon to catch.

For those that may not know, the Pokemon this time around is Duskull, a Ghost-type Pokemon. If players have already explored the Cobalt Coastlands, then they should know exactly where this location is.

Specifically, the photo was taken at Deadwood Haunt, and if players go to this exact location during the day, they'll notice there's not a single Ghost-type Pokemon in sight.

Rest until night at the Coastlands Camp to spawn some Ghost-type Pokemon. Players may find a Dusclops or Dusknoir when looking for Duskull, the former of which they'll need for Mission 10. For now, look for Duskull and catch it.

As an aggressive Pokemon, Duskull will immediately go on the offense, so bring Mud Balls or Spoiled
