My Little Pony Micro-Series: #7 Cutie Mark Crusaders: 01/03/19
My Little Pony Micro-Series: #7 Cutie Mark Crusaders by Ted Anderson is a standalone adventure with the three cutie mark crusaders in the days before they earned their cutie marks.
While out looking for something they're good at (good enough to earn their marks) they come across a giant gem. The gem ends up not being a gem. Instead it's a creature that can mimic other shapes.
The comic ends up being hard earned lessons for both the fillies and for the creature. For the girls it's learning that one shouldn't abuse a friend's talent for one's own amusement. For the creature (and my extension, artists / other creatives) the lesson is to learn when to say no.
In terms of plot, it's pretty thin, but the lesson is still an important one. And it's presented in an entertaining fashion.
The next issue is Princess Celestia by Georgia Ball (2013)
