I want to tell you about someone you remind of a great deal. His name was Yoda. He was small like you, but his heart was huge, and the Force was strong in him. He once said to me, "Size matters not". That's how he talked. He would speak in riddles.
THE BOOK OF BOBA FETT | 1x06 "From the Desert Comes a Stranger"
"I did research on the culture and environment of Tusken Raiders; I researched [the] 'sand people.' That is what Luke Skywalker calls them, 'sand people.' Anyway, my goal was to avoid ASL (American Sign Language); I made sure it became Tusken sign language based on their culture and environment."
"We kept it really simple in terms of the hand shapes that were used. When the Tusken sees the Mandalorian, this is the sign: using this flat hand shape, it outlines the gaps in the Mandalorian's helmet."
— TROY KOTSUR, the deaf American actor who developed the Tusken sign language and who played the first Tusken Raider to use it on-screen
