My big plans for these guys (I probably had around 30) included a tidal wave of green slime. The slime came in a plastic can and had a wonderful aroma halfway between play-doh and shampoo.
The slime flowed thick that day, my friends, and left my M.U.S.C.L.E. men corroded with a flaky green crust that didn't budge for at least 15 years.
