The SDCC exclusive Vinyl Scratch can be found for sale here. Don’t expect this figure to last long.

[Update]  The description:

This pretty-as-a-picture pony will be the star of your collection! He’s got the same silky hair as the disc jockey star – but this special edition pony figure is decked out for a VIP party. Don’t miss this one-of-a-kind version of your most fabulous pony friend! Delightfully decorative pony figure looks like the DJ Pon-3 character. Prance him around with other pony friends (sold separately) or display him in your collection.
