Original Description:
 
With points I mentioned in the description of the previously uploaded map of the Griffish Isles I drew for a Tails of Equestria online role playing game this character may come as very little surprise to some of you ;)
 
While the player group headed northward through the Shetland Forest they met this mysterious hooded pony. Seen from the distance only and with the cloak and hood masking the theoretically possibile but in any case covered horn or wings the group cannot even tell for sure if this pony was an earthpony, unicorn or pegasus.  
Later in Trottingham they learned stories about a mysterious pony who the ponys of Trottingham refer to as Robbing Hooves. This pony is said to have repeatedly robbed food stores to be shipped to the Griffish Empire at fall time (in accordance with the treaty that put an end to the war between ponys and griffons 27 years before) and with the food stores turning up again when food was running out during the long and cold winters on the Griffish Isles (no pegasi weather controll there in accordance with aforementioned treaty).  
Unsurprisingly opinions on this Robbing Hooves are divided and not exclusively negative in Trottingham. Keepers of the law however are concerned about this pony’s actions posing a threat to the peace with the Griffon kingdom.
