Topps, the candy and trading card company, released a batch of candy heads in conjunction with the release of Return of the Jedi.
There were six heads (of which I have five, showing the popularity of the ewok, Wicket, who was sold out when I purchased the other heads). There were some obvious character choices, such as Darth Vader, two different ewoks, and Jabba the Hutt. Admiral Ackbar also seems like a fairly obvious candidate, but Sy Snootles? Why her over a Gammorian Guard, or the heavily marketed Klaatu, or even R2-D2 or one of the Imperial Guards?
The candy was obtained by opening a hatch on the bottom.
The candy itself, which was flavored and textured along the line of Sweet-Tarts, was molded in the shape of two different style of ewok, Jabba, Darth Vader, C-3PO, and R2-D2, but not Sy Snootles or Admiral Ackbar.
There had previously been a larger series of candy heads marketed for The Empire Strikes Back. These heads also had necks with The Empire Strikes Back logo embossed on them. The necks could be turned to align two holes through which the candy was dispensed, which was not in the shape of any Star Wars characters.
