Here, Starshine Twinkle and Shatter are taking care of “babs”, Starshine is holding Peridot (One of my new, canon character based O.C.‘s, I have many more on the way) and Donnie is playing with Peri. These two ponies actually volunteered to come here since they’re scientists/technicians so they’re trying out the effects of one of the various potions between the two pegasi and it’s a mental regression potion. But all the while, they’re getting some relaxation. Shatter is on diaper duty and tending to any foal who needs a change.
 
And Peridot is an adult, she’s smaller than the average size mare so she’s just as old as the two other mares but younger.
