Glo Worm

Glo Worm is a stuffed toy for young children, designed by Hasbro's Playskool division, and made in Pawtucket, Rhode Island. Introduced in 1982, the plush, 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.

The original toy, upon release, was such a success that Hasbro released a new Musical Glo Worm and Glo Bug in 1984, and a Glo Butterfly in 1985. A series of story books, night lights, videos and other merchandise was also produced until the early 1990s. However, in late 2005, the product was criticized for harming children; its plastic head was softened with phthalates, which can be dangerous if swallowed by children. The Glo Worm is still made today, although with an updated appearance.
