In case anyone is wondering, there is no such thing as Sus Magnus. Wild boars are classified as the same species as the common pig, just without the 'Domesticus' part, which I thought was rather unimaginative.
Several years ago, I played an online game called Mabinogi. At one point, they announced the addition of several new pets to the game, including a pig. I was hoping the pig would be rideable, as some of the pets were, but unfortunately it ended up being one of the basic pets that just followed you. I still want a rideable pig.
