Rainbow Rocks, Dazzlings enter the gym, Rainbow grabs a chocolate chip to throw at Twilight to get her attention to point out the Dazzlings.
 
Kinda funny to watch Pinkie’s reaction as Dash does this. Something I love about the show (MLP:FiM) is just watching how alive these characters are with their adorable little interactions - this seems to have extended to Rainbow Rocks, at least in this case.
 
All of this happens in less than a second:

(this one)
 
Pinkie just gave Rainbow this confused look: >>1108605
 
So Rainbow seems to respond with this look? Or maybe it’s Rainbow’s “I’m about to throw a chip at Twilight to get her attention” look :p
 

 
Attention to detail - I love it!
