"Her name has been spelled different ways over the years.
In 2016, Tommy Andreasen said the spelling of her name was Mistaké.
However, there have since been two canon books released, The Book of Spinjitzu and Garmadon Rulez!, which have spelled the name as Mystake, as do the 70657 Ninjago City Docks (on the box and in the set description).
Additionally, the creators have used the two spellings interchangeably since then.
The credits for seasons 8 and 9 also spell it as Mystake, and while the credits have had errors in the past, these credits spelled Dareth, Skylor, and Ronin's name correctly, which had been misspelled in previous seasons' credits.
Andreasen later stated that the show takes precedence over past creator statements, which would presumably apply to canon books as well. He also stated that he does not want to contradict official publications with his own spellings and ways of referring to things."

Why are there Legends of Chima characters???
No ice people from the Ashtherah series thing (not idea how to spell)
Aspheera, Char, Clutch Powers, Vex etc.
The Pyro Vipers and the Blizzard Samurai simply don't have names and due to that are not featured

Laval and Cragger from Chima appeared in season 5 as a cameo so I decided to include them
I'm pretty sure it's Mystake
