Rubber Mares
From sNr Wiki
sNr also had rubber ponies in the past, called Humares. They have been stalled in the guest area rather than the main stalls. Being a rubber mare completely robs the person of their identity and provides a standard, consistent look rather than the individual look that can be achieved as a standard pony.
There is a powerful rubber mare suit available to purchase in the shopping area at sNr for just 15L. It provides everything they need including the suit and integrated bridle. However this is not the original rubber mare suit.
Since 2018 sNr doesn't host rubber mares anymore, ponies or mares wearing a lot of rubber are still welcome of course.
