as for other stuff I kept trying to the the blue lightsaber spoon from a few years back for my niece ... she kept getting red ones.
As a kid I tried to get all the glow in the dark puzzles that Captain Crunch had in their boxes, I think I got them all but one. I really wish I still had them ... I loved how the glowing part was really a hidden picture that you had to turn the lights out to see.
There were tons of stuff that I didn't care if I completed the set just as long as I got something lol, little things to write secret codes with numbers from Kelloggs, or coin holders of Fred and Barny from fruity pebbles.
