During one of the side quests in Pokemon Legends Z-A you will be asked to find a dozen lost Spewpa. All of them are inside the museum and pretty easy to locate due to their appearance as they feel really out of place.
There are 12 Spewpa that are lost in the Lumiose museum. Press A to investigate each one for a successful pick up. Start the quest by heading to the Lumiose Museum and speaking with the Bundo.
Spewpa Location #1 and #2
The first Spewpa is sitting on stairs, right behind Bundo. Grab it and go up the stairs where the main museum offerings are.
As you are heading up the stairs, you will find another Spewpa wedged between the off white couches.
Spewpa Location #3
On the upper floor of the museum, a Spewpa is found among the exhibitions immediately to the left of the stairs and in front of the giant painting.
Spewpa Location #4
Look up from the third Spewpa and you will easily see the fourth one sitting on a sofa in the left right corner of the room.
Spewpa Location #5
Directly in front of the fourth Spewpa, you can pick the 5th Spewpa from the holographic display.
Spewpa #6, #7, and #8
Three Spewpa are in the next room of the exhibition.
Spewpa Location #9
Keep going into the next area and you will see another Spewpa under some old paintings.
Spewpa Location #10
From the 9th Spewpa head straight and to your right will be a statue with its head being a Spewpa.
Spewpa Location #11
Directly in front of the 10th Spewpa and the large Pokemon statue.
Spewpa Location #12
Take the next stairs down where you will find the 12th and final Spewpa in the right corner behind the small blue display.
For your troubles of finding all 12 Spewpa in Pokemon Legends Z-A you will get 3x Normal Gem, and 1x Wise Glasses.
