Jetpacks! A very fun request by Flames88.
 
Their tails are tucked away for safety reasons, and they are otherwise fireproofed (magic) so no need to worry about their wings and stuff being near fire. Also, AJ is not wearing her hat due to the fact that she would rather not lose it while flying around. Pinkie is upside down because it’s Pinkie.
 
I really hope I didn’t miss anything in this artwork, it can be easy to miss small stuff in a large artwork with multiple characters.
