Krakkanon

Krakkanon is a rare elite kraken found all over Pandaria. The kraken appears in the locations that have an abundance of fishing pools, which can be found out by talking to Ben of the Booming Voice at Halfhill in the Valley of the Four Winds.

The fishing pool has a roughly three hour respawn timer.

Drops
Like the shared tap rare mobs on Isle of Thunder and Timeless Isle, anyone on the kraken's aggro table will receive loot.

Krakkanon drops:
 * A stack of 20 Pandaria fish (whichever is in the pool)
 * Flying Tiger Gourami or Mimic Octopus or Spinefish Alpha (as appropriate for the area)
 * Nat's Fishing Journal (rare)
