SLIME BY MATTEL:
Slime was a product manufactured by Mattel and introduced in the winter of 1976. Slime consisted of a viscous, oozing green material made primarily from guar gum and sold in a plastic trash can. Different variations of toys were released over the years, including toys containing rubber insects, eyeballs, and worms, Masters of the Universe Slime for Hordak's Slime Pit playset, and, of course, the "Ecto-Plazm" (sic) sold with select figures in the Real Ghostbusters toyline.
