Rare loot from Savage Gift.

Notes:

You have a rare chance of obtaining this angry yeti from Savage Gifts that you can buy from your Draenor Garrison Events Coordinator during the Feast of Winter Veil, which occurs around mid-December to the start of January each year. Each gift costs 5 Merry Supplies, which is exactly the number you get from one day's worth of Winter Veil dailies. The dailies that award Merry Supplies are listed here. See the World of Warcraft Events Calendar for precise dates for this festival.
