Dye Lock-lids (jumping bean inside)

[Paradox313]

I just bought some Dye Lock-lids new from a store 130 miles away for $15 (hell of a deal), when i got to my car i opened the box and looked inside a freaking mexican jumping bean was in it hopping around
i have no idea how it got there. before i got any pictures the little bastard died and flew away into the wind.
comments and suggestions on how this happened?
