What are M.U.S.C.L.E.s? M.U.S.C.L.E.s, also called MUSCLE men or MUSCLE things, are small PVC figures with an "intergalactic wrestling" theme (M.U.S.C.L.E. is an acronym for Millions of Unusual Small Creatures Lurking Everywhere). Produced by Mattel, MUSCLE toys were available in the mid-80's, from 1985 to 1986. M.U.S.C.L.E. Figures/Assortments MUSCLEs were available in the familiar 4-packs , 10-packs and 28-packs , and had a M.U.S.C.L.E. Wrestling Ring accessory , among others.
