MK wakes up to a perfect life... TOO perfect. Evidently, he's defeated the entire DBK family and everyone treats him like a hero. MK soon realizes everything is not as it seems, but that he's living in an illusion brought on by being trapped in the nefarious Calabash, an ancient magical device wielded by two mischievous demons. MK must shake off the illusion to defeat his comically weird enemies.

Everyone in the city is abuzz with the talk of an upcoming street race that will grant the winner "immortality". Mei and MK enter the race but a disagreement has them competing against each other.

The Monkey King!

DBK's family's found a mysterious power source that will allow the brute to reclaim his former glory. But the strange item is locked behind an impervious ancient gate that needs a key... the same key that was given to MK as a 'thank you' for saving the city over and over. Now, it's a game of cat and mouse as DBK's family tries to get the key and our heroes attempt to keep it out of their hands.

The mysterious and powerful Macaque shows up in the city, helping MK thwart an evil cloud of smoke. He offers to train MK.

It's up to MK to rise up and help the Monkey King before all his power is gone.
