Metallic is the theme. The can is the trick, in the can are the treats. Metal can (recycled), beads with silver stripes.
Also: Copics, can recycled, yarn, beads.
Treats: snakes, frogs or anything slimy...
The trick is to open the can (of pineapple etc) at the opposite end to the pull tab. When it is washed and dried, the can is filled with treats, a circle of card is put in, the can is then sealed with hot glue gun, and a circle of decorative card (or a greeting) laid on the outside so they can't tell it's been doctored.
Maybe you can buy cans filled already, then just decorate. I find men especially love these cans.
