Boglins were characterized by their unique packaging (a cardboard box with a plastic "cage" entrance) and by movable eyes and mouth. Boglins were manufactured by a number of companies including Action GT and Ideal and distributed by Mattel. They became very popular in both the U.S. and the United Kingdom, and their popularity is believed to have reached its peak thanks to a deal with Kellogg's in 1989, to use them in promotions contained in, and on, boxes of Rice Krispies cereal, including rubber stampers, stamp collections, cut-out masks and an exclusive set of Mini Boglins.
Boglins were also characterized by their varying "genus" and unique form, which entailed a pair of arms, no legs, and a flatish body. The cult status of Boglins in the past has been so great that they have made appearances in other media.
