Blizzard Entertainment originally introduced Murky as the first World of Warcraft murloc pet only obtainable to those who attended BlizzCon 2015 who were given a card code in their Goodie Bag.

Murky became one of the Heroes of the Storm playable heroes, and he is now a cute NPC in World of Warcraft: Legion. During the quest Nature vs Nurture, Murky bubbles up and follows you to talk to other tadpoles. The bubble buff says — Safety Bubble: “Invulnerable to damage. Cannot attack.”

Murky is accompanied by D.E.H.T.A. King Mrgl-Mrgl.
