Grrbrrgle

Grrbrrgle is found at inside A Restless Crate, washed up on a small island off the Sunset Shore off the southwest coast of Talador. A few Shipwrecked Smugglers landed with their cargo on a small boat, but none of them made it, and a warning note next to the crate explains why:

Not that players are known for heeding warnings, interact with the crate anyway to release Grrbrrgle, a rare deep sea murloc. The murloc drops Mrglrgirdle and 10-20 Garrison Resources.
