Oh, wow! I've never seen these before.... I was over at Imockery and they're doing a special on Halloween Candy. Apparently there's this candy that's marshmallow eyeballs with stuff in the center, like lemon, strawberry, or raspberry filling. You squeeze them and it OOZES out nicely!
I've GOT to find some of these! :)
Granted though, the outside doesn't look much like an eye.. don't seem any pupils or anything, but still!
Anyway, if you're curious, you can view the whole article here
