Cotton Cloudy just had an awesome background appearance in “2, 4, 6, Greaaat”. Look closely during the cheerleader performance. And who is Serena?

I miss Princess Erroria and Cotton Cloudy too! Wasn’t it Peach Fuzz’s mother is Serena?

This is funny

@EPPony
 
Not to mention we finally know something about her personality and how her voice sounds!  
I still need to draw her after that amazing reveal. :D

@CMC Scootaloo  
She was certainly a bundle of cuteness in this episode due to that.

Peach Fuzz is such a fascinating filly, she is always so optimistic, even if the times are though.^^  
I love her. <3

I think I know who patient zero is^^

@KingKek42  
Rob Renzetti huh? That’s rather ironic.

@Toyminator900  
Eh, not quite. These have more of a ‘Rob Renzetti’ look to it

And now this. If anyone comes up with a good name for it, I’ll tag them.

@KingKek42  
Yeah sort of, the images look simpler.
 
Here’s one from “Flutter Brutter”  

@Toyminator900  
I must have just not noticed it then, because I only remember seeing it in these three episodes.

@KingKek42  
How about
 
“Show photo”?  
_{^{(so creative)}}
 
And I believe it’s been in the show before, and I’ve always liked this style actually

We really need a tag for this new art style. It’s shown up in every episode so far this season.

@EPPony
 
Since Spike isn’t a pony, he wouldn’t be in danger (like that IDW comic where he doesn’t get sick like everyone else).

@FanOfMostEverything  
Peach is always optimistic.

@kinghearts  
Because it was picture day, darn it, and she was going to make the most of it, hives or no hives.

Why is one of them smiling???

@09MurphyM  
My guess is that the CMC, Diamond Tiara and Silver Spoon have different class times than these filles/colts.

Funny how it’s simply the background ponies that got sick.

H0ives. :D
 
I wonder what they were exposed to, to get it.

@Background Pony #1CCC  
Actually, I am pretty sure it is lupus :)

Love how Peach Fuzz is the only one smiling.

And Cheerilee didn’t notice until then? Teacher of the year, ladies and gentlemen.

According to Horse MD, horse hives are the result of a systemic reaction to allergen, mostly animal feed, insect bites, pollen, molds, deworming compounds, antibiotics, bedding, heat, light or even excercise. They are characterized as localized soft pit swellings on the skin, as seen in this evidence photo.
 
Fortunately, you can easily root out the cause after interdermal testing and can be treated with some anti-histamines (e.g. Dexamethasone) or steroids
