|First Appearance||The Golden Weapon|
A tea shop in Ninjago City sells several varieties of tea, including some with special properties.
As a test, Kai had to complete the obstscles in Wu's monastary before Wu finish his tea.
When the Ninja and Nya infiltrated the Serpentine's Underground Fortress, a battle erupted between the Ninja and the snakes for control of the Four Silver Fangblades. During the battle, Master Wu mainly observed his pupils' progress from the shoulder of the Samurai Mech and enjoyed a cup of tea. When a Venomari Scout tried to climb on the mech, Master Wu poured hot tea on his head.
While fighting the Serpentine atop the Serpentine Train, Chokun climbed onto Nya's Samurai Mech. Instead of fighting, Master Wu offered some tea to the Constrictai Soldier - when the cup was full, he punched Chokun off the Samurai Mech and deftly caught the cup without spilling a drop.
During the escape from the Great Devourer, Kai threw Master Wu's teapot off the Destiny's Bounty to try and increase its speed. Lord Garmadon was later seen ordering Traveler's Tea from Mystake, but abandoned it when he saw the Ninja battling the Great Devourer on television. After the Great Devourer's destruction, Master Wu found his teapot amid its remains, commenting that the tea was still hot.
Once Master Wu and Nya heard of the Grundle situation, Master Wu decided to visit Mystake for Tomorrow's Tea. With the tea in their possession, the pair hurried to the comic store where the Grundle was spotted, finding it menacing the de-aged Ninja. Lloyd used the tea to reverse the de-aging magic that revived the Grundle and reduced his friends to children, but was also aged to teenage years due to being caught in the "explosion" of the tea.
At Dr. Julien's lighthouse prison, he explained a flashback about his death. When Zane questioned why he is alive as he used his memory switch to remember the death of his father(Dr. Julien) Dr. Julien explained that what Zane did not see what that Samukai was reviving Dr. Julien with Resurrectea. Samukai wanted him to create viechles for his Skulkin Army. When the revived Dr. Julien refused, Samukai trapped him in the lighthouse prison and placed a leviathan to keep guard that he did not escape.
Following the loss of his brother, Wu retired as a master and opened a Tea Shop called Steep Wisdom. Then, he instructed all the other ninja to advertise the tea shop. The ninja were not supposed to use their elemental powers to help, but did they listen?
When Master Wu and the ninja returned to Steep Wisdom, the ninja were surprised to see that the land was no longer theirs. They learned that Wu sold his business to Cyrus Borg for more advanced veichles to help them defeat Morro and the ghost army.
One of Mystake's special blends, Traveler's Tea is a substance that enables users to warp to certain locations, including other realms.
Tomorrow's Tea is another one of the many special blends offered by Mystake. When used, it can rapidly age things and undo the effects of time-reversing magic.
