Original Description:
 
Meet Tundra Trek ;3
 
She is a Russian pony/snow leopard Abyssinian hybrid, who lives out in a snowy winter village in the mountains of Equestria ;3  
She is a very athletic and fast pony, very skilled at going through the snow and climbing up trees, and has very fast reflexes.
 
Tundra works as a tour guide for the region, helping travelling ponies to get to know more about the land and the area, as well as making sure that they are kept on the safe roads. this also means that she is skilled at tracking others and being there to rescue them.
 
A very chill (pardon the pun lol) mare that is very easy to get along with, she often likes to hang out with the locals for drinks and fun during the nights.
 
The gas mask is for when the weather is very harsh, as it helps her breath during the snowstorms. The spikes and gothic look to it are her own modifications to it.
