The Spider Queen teams up with a mysterious, shadowy villain to collect powerful artifacts in order to defeat MK and his legendary teacher Monkey King. And the mysterious benefactor, who will be revealed as Lady Bone Demon will emerge from the shadows with a plan to collect mystical items throughout the city in order to construct a device capable of defeating MK once and for all.
A new game sweeps across the city, but instead of fun and frivolity, the game is actually a virus that knocks out everyone who plays it, leaving the "Cloud" free and clear to be pilfered by one of Spider Queen's minions - Syntax, the Tech Spider! It's up to MK to swing into action, shut down the cloud, and wake up the city.
MK receives a mysterious call from Monkey King. Turns out, he may have accidentally knocked over a "Celestial Dumpling". It's streaking toward earth, and if it hits... well, everything will be destroyed. To contain the Dumpling, MK and Tang must find a Mystical Vase at Flower Fruit Mountain, a place replete with mystery and danger.
Pigsy has replaced the Monkey Mech game with Ping Pong and gets wildly addicted. MK has to break Pigsy from his addiction in order to save his shop. Meanwhile - Sandy accidentally gets put to sleep with a supercharged sleepy time tea. When a box, marked "from Monkey King" arrives, Mo finds himself having to take care of a bunch of Fruit Babies that are running rampant all throughout the boat.
Speedy Panda stores have appeared everywhere along with their biker gang delivery boys. Things boil over until a "food war" is declared. "Food critics" arrive, and Pigsy and friends must compete in a Food Olympics against Speedy Panda... which just so happens to be owned by Jin and Yin, the Gold and Silver Demons!
MK accidentally shrinks himself and falls down the drain, into the sewers, and finds himself back in the lair of the Spider Queen. Trying to escape, MK finds a young girl in need of rescuing. However, she's really Lady Bone Demon in disguise! Meanwhile, Tang has become a food critic, and Pigsy bends over backwards to make sure he's pleased.
MK is stuck in his training. He's not really advancing in his power set and feels like he'll never really be the hero he needs to be unless he goes through exactly what Monkey King went through. When he finds a VR video game that emulates the Monkey King's battles, MK jumps in, hoping to "live" Monkey King's life in order to be a better hero.
Our heroes attend a shadow play, secretly run by the Macaque. Using a magical lantern, he imprisons the other heroes to toy with MK. MK feels a strong connection to the play, about a Warrior abandoned by his Hero. When Macaque finally reveals himself, he torments MK for not realising his friends were missing. Macaque declares he will be MK's teacher, even if MK doesn't want him to be.
MK has got a bad case of the hiccups. Real bad. Because of his powers, every time he hiccups it causes a giant earthquake! There's only one thing that can cure it, a special tea made from a flower that only Sandy can procure from a dangerous location. While he attempts to find the leaf, Huntsman; one of Spider Queen's henchmen, is in pursuit, trying to steal the flower for his master.
MK has learned the power of TRANSFORMATION! Kind of... When Spider-Bots steal Pigsy's sign, MK needs to use his new powers to get it back! Down in Spider Queen's lair, MK finds she is trying to build a weapon to fight her old ally, Lady Bone Demon. He knows he needs to stop her, but maybe there's hope for his old enemy?
After gathering all the secret ingredients, Lady Bone Demon creates a POWERFUL BONE MECH which she uses to attack MK while he is out training. Even though MK has gained new powers, Lady Bone Demon has figured out how to defend against each one and everything turns sideways as MK is defeated! Now our hero desperately needs help to make it out alive, and find some way to come back and save the day!
