Original Description:
 
The new generation of ponies is very reminiscent of “Filly Funtasia”  
There are 3D ponies who go about their business. There is an evil villain who wants to do something evil, but cannot get out of captivity. He has a henchman to whom the villain promised something, and he, licking the villain’s ass, tries to please him  
But the henchman is not familiar to the main ponies and is considered a friend in their circle….  
Since Twilight is shown as small, the events with Opaline apparently took place after Twilight’s coronation, but before her tall version  
Opaline I think related to Flurry Heart  
Maybe she’s a sister or daughter
 
In the cartoon “Filly Funtasia” the henchman communicated with the antagonist through a mirror…  
Doesn’t it remind you of anything?
