So while running around the new event area, I notice a tag on one of the shroomseras. I then checked another one and they had it too... So I decided to look more into it. 

So this is what I came up with:  
Brown Tag - For baby shroomseras. 

Yellow Tag - For green shroomseras. These are shroomseras that are not ready for the Fullbloom Celebration.

Blue Tag - For mature shroomseras. They are ready to go to the Fullbloom Celebration. I'm not sure why some of these shroomseras have the blue tag, yet their cap is green (I though yellow capped ones means that they are matured). Are they perhaps like matured but not fully matured?

And also idk why the shroomseras who are in the summer camp (from what I've seen) have like symbols on them. Is it a sign that they are not in Heaven's Reach anymore or? And the shroomseras who are out have their tags green. What does the green mean?

However I'm not sure if it these symbols are just for like the shroomseras that we encounter in the new story. I only took pictures of them.

  
But yeah it's so sad to see the shroomseras being labelled with a tag. It reminds me of domesticated animals being tagged :(

  
(Also these pictures are taken in like the lowest quality so I'm not sure if there are any other details in the tag where you use higher quality.) 





Shroomseras are labeled?
