I’ve seen a few players with this mount, and the fact that it isn’t two player feels weird. In addition to paying $11, they have to do a quest. And judging by the limited amount I’ve seen, I’m going to assume it isn’t an easy quest.
There are two ways this could be implemented. Extend the saddle back a bit and include a handle bar. Or have the second player be holding onto the tail with one hand for dear life.
