This quest has some ties to stories such as the 2008 movie Forbidden Kingdom.
<Quest speech>
Anduin Wrynn:
According to my research, the pandaren long ago made a special mallet that was intended for the Divine Bell. When using the mallet on the Divine Bell, the pandaren monks were able to create pure harmony. But then the Monkey King one day decided to steal the mallet and hide it as a prank. There is no record of the mallet after that.
What I did find, however, was the final resting place of the infamous "Monkey King." The tricky part is, he was frozen in jade while dueling a mogu that history names "The Jade Warlord." I found an incantation to release these two from their prison. But it will release both of them. Once I cast this, defeat the Jade Warlord before he can get his barrings (bearings?).
<Talk to Anduin to begin>
Anduin Wrynn:
Here goes nothing. My research did not have nice things to say about this Jade Warlord. Be ready for battle.
The Monkey King:
Iiiiiiiiii'm back Wikkets!
<Quest completion text>
The Monkey King:
You come asking for the Monkey King?
Let us see how well you ookin' sing.
Who are you, so tiny and boring?
Your cause is silly! You leave me snoring.
Three riddles I will ask,
These riddles are a task,
Finish each without pause,
And we shall see if I help your cause.
<Completion leads to more talking>
The Monkey King:
Wooo hoo! Son of an Ook! Pins and needles, pins and needles. Legs are asleep. Hand is asleep. Nibs are asleep.
Anduin Wrynn:
Ah... your grace?
The Monkey King:
Ooo? Grace? I not an emperor, little thing. You stand before the Monkey King!
Anduin Wrynn:
My apologies. My name is Anduin Wrynn. This champion and I need your help.
The Monkey King:
Help? You saved me from eternity trapped in jade! I'm gonna throw you the biggest party ever made!
Anduin Wrynn:
Thank you, but this is hardly the time for a party. A dangerous war leader named Garrosh has found the Divine Bell. We need the Harmonic Mallet to counter it.
The Monkey King:
Oh... the missing Harmonic Mallet, eh? Such a silly name. So you come find the King because he is to blame?
Anduin Wrynn:
Well, my research said you were the last one to-
The Monkey King:
Ah ya ta ta! Don't worry, you in the right place. But let's first see if I like what comes out of your face.
