Forever a Spike.
And I don't think 20% of a moustache forms a beard but whatever.
The Fabulous serpent is called ´Steven Magnet´ btw and Scootaloo has the hots for him. [link]
(I was there before he was a forced meme. These subtitles are made by youtube transelator. It's insanely hilarious because it sucks horseshoes.)
Dash is popping up because she thought she was called.To understand what's happening it's required to watch Friendship is magic; Boast busters.
Within the episode, the background pony Carrot Top appears with her orange hair, later on appears green haired and is insulted by Rarity who said 'Green is such an awful awful colour'. After this she return to orange. I didn't think it would be any good for a clothing-artist to dislike a colour just out of personal taste. It matters what the match is if colours work. So I made her positive about the colour 'green'. However, if Rarity dislikes a colour it's usually green.
I was surprised it took so long for people to notice Carrot Top's hair changing within the episode.
If you want to imagine this in voice, I'd prefer going with Carrot Top's voice in 'Swarm of the Century'. It sounds very cute.
This took forever. Be amazed the background skills of the great and powerfull PepperSupreme!! (Lol, I got lazy there)
