|“Mercy? Never heard of it.”|
|Affiliation||Tea Shop Owner|
|Voiced by||Mackenzie Gray|
Sensei Wu visited her shop, requesting Traveler's Tea. At first she claimed not to have heard of it, but upon receiving payment, brought the tea out from behind the counter, warning him of the consequences.
Lord Garmadon entered Mistaké's shop, asking for Traveler's Tea. She told him that only a fool would request the tea, but after realizing that his request was serious, she changed her mind and went to retrieve some from the back of the shop.
When the Ninja were reduced to children and menaced by a resurrected Grundle, Sensei Wu and Nya went to Mistaké's shop with a request for Tomorrow's Tea. When she went to check her supply in the back, she was unable to pinpoint the tea's location. As a result, Nya and Sensei Wu were forced to rush to the Ninjas' aid upon finally retrieving Tomorrow's Tea.
- Her name is a play on the word "mistake."
