I would like to see a Raptor Mount skin with a Tophat and a Monocle.
A party Springer Mount might be nice, where it has the typical party hat (cone shaped) and one of those party whistles (where when you blow into it, it inflates and unrolls) which it blows every time you use the attack/dismount skill.
A mini Shashoo with an Admiral Hat would also be nice.
A home instance Choya-pinata where you smash it daily to get fruit like bananas, mango, strawberries, melons, etc.
