It just hit me that all this new information out of nowhere from no one in Eponia was odd, so I realized there should be some sort of explorer character who probably writes all this stuff down and publishes. And thus I made Professor Fududdle.
Also a bit on his personality: He's very active and curious about everypony and the world around him. He's entirely willing to get to know new ponies even if they're from somewhere he's been before, so long as they seem interesting to him. He's very friendly because of this, and polite. He is very difficult to anger, however he is skittish around ponies that seem obviously dangerous.
