Tusken Raiders (AKA Sandpeople) are easily startled and make donkey noises. They need a friend. You could be that friend.

I have had the most luck including "tskn, a tusken raider" in the prompt, with ~.92-.94 strength. Any lower and it often screws up the mask too much, and any higher makes the lora less flexible overall. 

Have fun, and please share your creations!
