Little White Stallion Bridle & Little Ivory Raptor Whistle
The Little White Stallion Bridle and Little Ivory Raptor Whistle are both obtained from the Tiny Loot Card. Depending upon the player's faction, they are awarded either a tiny stallion mount (Alliance) or a tiny raptor mount (Horde).
Each loot code grants a total of 50 charges, which are consumed each time you use the mount. The charges are stackable up to 250 (5 loot code turn-ins).
Although it's a consumable charge mount, this mount behaves as a typical mount and is affected by all things that affect mount appearance or speed; however, it does not count towards your Mountain o' Mounts achievement.
Tiny is a very common loot card, with an insert rate of 1 in every 11 booster packs.

The Tiny Loot Card is found in packs from the Scourgewar Expansion Set.
At 1 in 11 packs, it's a pretty common pull. However, Scourgewar booster boxes are going for about $60.00 these days, so if you were buying packs to get it, you'd end up spending about $25.00 to $30.00.
