Socket Poppers (ERTL) Checklist

If you built three characters a minute with no duplications and worked continuously for two years, you couldn't complete all the possible combinations offered by just two Socket Popper characters! Assuming there were no duplications in their work, one trillion people each working continuously for one trillion years could complete less than one-billionth of the possible combinations offered by all 16 Socket Popper characters!
