Misty Rosas played Kuiil in three chapters of The Mandalorian.
If all you know about Kuiil is that actor Nick Nolte voices him, you are missing a large part of the story. Behind the Ugnaught makeup and animatronics was actress and creature performer Misty Rosas.
Over the years Misty has brought several non-human characters to life including Amy the gorilla in the 1995 film Congo and Beary Barrington in the 2002 film The Country Bears.
Rosas has also done stunt work on films such as Practical Magic, Van Helsing, and The Hunger Games: Catching Fire.
