IM4-099, or "Face", accompanies the stormtroopers in their door-to-door search. Seeker probe droids were part of George Lucas' original vision of Mos Eisley law enforcement, as seen in early production paintings by Ralph McQuarrie.
Listen carefully as Threepio peers out the door. You can hear a droid detector warble.
In the background is a custom-made treadwell droid named WED-9-M1, or
"Bantha." This stubborn worker droid is owned by the proprietors of Docking
Bay 94.
It's a crowded speeder lot. Taking the credits from Luke is the comic-faced Wioslea, a member of the Vuvrian species. Wandering through the scene are R4-E1, which is BoShek's droid, and the frazzled business droid CZ-3. CZ-3 is featured in my short story Spare Parts, published in The Official Star Wars Adventure Journal #11.
One of the new ships added in the background of the special edition looks curiously similar to Kyle Katarn's Moldy Crow.
Wandering into frame are the Hunchback -- which Decipher made to be a separate character, but is most likely the Snivvian Takeel -- the Bantha droid from the previous scene, and the stilt-like avian legs of Kal'Falnl C'ndros, a Quorsav trader.
Yerka Mig wanders into frame (or, someone who wears one of those popular Ralltiirian jackets). As does the rodent-faced Nevar Yalnal. If you look carefully, the Nimbanel Mosep starts pawing Luke's landspeeder before the craft is even cold.
As Garindan follows the heroes, several familiar faces can be glimpsed in the background. Sporting a distinctive haircut is the Corellian trader Brindy Truchong (1). That persistent blowhard Doctor Evazan almost rubs shoulders with Ben as they walk through the corridors (2). No, that isn't Greedo, but another Rodian thug named Thuku (3). And speaking of thugs, there's Jabba's tall-hatted accomplice (4).
Rodians seem to dress alike, since another Greedo look-alike enters the frame (1). One of the cantina's Saurin aliens is outside (2). That's the back of Solomohal's head. Or maybe it's the Colonel. (3). And there he is again, Dr. Evazan. That guy just won't give up. (4).
Han's fingertip crosses Jabba's CG geometry in this shot, requiring a little dimple to form.
A tricky effects shot, as Han practically co-exists in Jabba's space. Look carefully at Han's gloves in his pocket. An animated rotto-matte meant to separate Han's gloves from the new elements in the frame has a very indistinct edge and is very shaky.
Yet another variation on Boba Fett's armor. The Special Edition version lacks Fett's skull-like shoulder emblem.
Well, I did for many years. The doorway Chewbacca is waiting for Luke and Ben in is clearly labeled in huge stylized numbers "94." Looking at it again, I don’t know how I missed it..
He walks down stairs, alone and in pairs, and makes a beepity sound. He's Artoo, he's Artoo. He's fun, he's a wonderful toy. He's fun for a girl or a boy.
As Han says "I’ve made a lot of special modifications on her myself," Kenobi makes the greatest look. He looks up at the ship while rolling his eyes. It’s pretty funny.
As Chewbacca gets into the Falcon, and puts his bandoleer away, watch his head knocks a pair of dice around. Also, note that Chewie took off his ammo belt. This is important.
