World's Smallest Glo Worm

The original Glo Worm

was a stuffed toy for young children, designed by Hasbro's Playskool introduced in 1982, the pajamaed worm body contained a battery-powered device that when squeezed would light up the toy's vinyl head from within, creating a soft glow. And now the Glow Worm returns in the World's Smallest Toys collection and yes it actually works.
