Glo Worms / Glo Friends
Remember Glo Worms and Glo Friends? These were rubber, plastic, or plush toys in the shape of worms, that would light up at night if you squeezed them. They were made by Playskool and popular enough to warrant story books, videos, key chains, night lights, and tons of other merchandising gimmicks. The line was so popular, that Wendy's joined the bandwagon in 1989, releasing 12 characters. They had names like Glo Snail, Glo Grannybug, Glo Cricket, Glo Butterfly, and Glo Bashfulbug.
