Garbage Can-dy? You got a little plastic trash can that you could open, and it was stuffed with SweeTart-like candy that was in the shape of trash. Bones, fish skeletons, opened tin cans...all the stereotypical trash shapes.
Like the person in the Flickr comments, I kept the trash can and used it in my dollhouse. And I also remember the Mr Bones version, a little plastic coffin with candy bones inside.
Weirdly, it was invented by Maus cartoonist Art Spiegelman when he worked for Topps. Supposedly he also invented Wacky Packs and Garbage Pail Kids.
