Notes:

In the upcoming second iteration of Plunderstorm, this treasure-laden crocolisk is purchasable from the 'Plunderstore', using currency earned during the event.

Plunderstorm is a 'battle royale' style feature is hosted on a different server and uses different characters and abilities to regular World of Warcraft - in fact, it's pretty much a different game that happens to use WoW assets, but the rewards are available in the regular game. See Wowhead's Guide for more information.
