I have a Star Wars minutia question.
In an early version of the screenplay for the first film there were "anteater-like creatures" on the streets of Mos Eisley on Tatooine. From the "third draft, August 1, 1975" [link]
... Several robots guide a small herd of anteaters down the street.
In the "revised fourth draft screenplay, March 15, 1976" [link], dated shortly before the start of principal photography on March 22, 1976:
Ben and Luke leave the speeder-lot and walk down the dusty alleyway past a small robot herding a bunch of anteater-like creatures.
And in the novelization, presumably based on that fourth draft screenplay:
Leaving the main street, they turned down an alleyway and walked past a small robot herding along a clutch of creatures resembling attenuated anteaters.
The "anteaters" seemingly did not make it to being built or filmed, but their removal must have been a late cut. Other obscure details in this scene mentioned in the "revised fourth draft" screenplay did make it to film, including the landspeeder dealer w/ an "insect-like" head and the tall, "spindly legged beast" that walks past the camera in the foreground.
My question: have any concept drawings or mockups for the herding droid and/or anteaters come to light? Is there anything unattributed from the production of the orignal Star Wars that might fit this description? Any behind-the-scenes mention of this?
Caveat, I don't actually know for sure if the dates or specific text of the screenplays linked above are correct, but they look credible.
