Puck Toys produced a set of three Muppet molding kits in 1977, and a further three in 1978. The sets were sold in the "Plastercasters" line in the United Kingdom, and "Creaform" in France. The figure molds were sold separately, or in large sets with three molds. Each kit included the rubber mold, a bag of plaster, paint and paintbrushes, and an instruction manual.

The 1977 set included molds for Kermit the Frog sitting on a tree stump, Miss Piggy holding a flower, and Animal playing bongos.

The 1978 set included Fozzie Bear holding a joke book, Rowlf the Dog with a bowler hat and sheet music, and Scooter standing at attention.
