That one scene is the one I really despise. A ronto taking up the entire screen is annoying enough, but they also basically wiped out an astromech to do so.I really wish the Jawa and Ronto slapstick with the passing swoop bike had been left on the cutting room floor. I like or can at least tolerate the new CGI additions to Mos Eisley except for the Ronto gag (appropriately named if you ask me) and the unnecessary pack animal lumbering in front of Luke's landspeeder at the start of the confrontation with the Sandtroopers. That was a bit much and nobody really had to see a CGI animal hide lurch by the camera during one of the most iconic moments of the original film.
And a pretty colorful and cool-looking R5 unit at that. I've always liked that Creamsicle-orange R5 that rolls by just as the Sandtroopers stop Luke and Ben and begin questioning them. It may be one of the few Original Trilogy astromechs that hasn't had at least one action figure made of it.
The one I'm referring to is R2-A5, while the orange one is R5-A2. The R2 got replaced by the ronto, not the R5. And it did have an action figure, but it was a build-a-droid.
