They are the star wars race most commonly attributed to being sex slaves, and are supposed to be the most beautiful in the Galaxy. I personally never really saw any appeal in the race, guess I'm not a head tentacle guy.

Need to keep the weight around 0.8 and up for this one, as anything lower tends to result in hair and more human features as the ai tries to correct. However this may be dependant on the checkpoint used, so feel free to experiment.

Seems to work with most skin colors but I found this is the best way to set up the prompts.

twlk2023, (choice of skin color) skinned alien girl, (choice of skin color again) skin, 2 head tails,

Also recommend you put hair and human in negative prompts.

It's not 100% consistent, as the tentacles really confused 1.5, but it works for the most part.
