Here is a rundown of the droids I made for myself...
R2s & R3s:
(note the one on the far right with one black leg and one blue leg... I made this droid just so I walked away with at least one of every part they had in stock)
The R2 w/the all-blue body is for future use with the R9 blue w/silver dome.
The R5 w/the all-green body is for future use with the R9 green w/silver dome.
I was going to make the R2 dome in silver w/red on an all red body, but they sold out of Right Red legs while I was there too.
The R7 trunk with all blue legs is for the R8 dome that's coming that's Blue w/Silver.
