Same as with the Dortmund mascot, I go for a “down to earth earthpony” with this mascot. This guy can use neither magic nor wings, but just plain dancing and he seems to enjoy every step of it.
I removed the miner helmet the mascot for the meetup in Dortmund had, created a cutie mark refering to Trotmania, gave him some rather colorful streaks to mane and tail and a bracelet with that cutie mark. Also, I put him on what I imagine a Trotmania dancing carpet might look like in Equestria.
The pose of the colt is inspired by this awesome image by Mister-Saugrenu.
