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 bottom from within, creating a soft glow while playing a soothing lullaby. The original toy, upon release, was such a success that Hasbro released a series of story books, night lights, videos and other merchandise that continued 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. In 1986, Playskool released a number of 'Glo'-based toys that glowed but were made of soft vinyl. These toys, collectively known as 'Glo Friends', were so successful that American fast food chain Wendy's in 1989 also released a series of 12 soft vinyl toys to advertise their chain.
