So today's mini-figs are from the M.U.S.C.L.E. (Millions of Unusual Small Creatures Lurking Everywhere) toy line. As a kid we always called them Muscle Men. I had one trash can pack of figures and all the rest I picked up at yard sales.
The green guy's head looks like it was whittled from a stick. The orange figure's arm features wood grain. The blue guy looks like he is wearing a pharaohs hat.
These are some of the weirdest MUSCLE figures I have. They each feature a strange head.
All three of these figures are very similar. Each one has a cylindrical head with a skinny ponytail coming out of the tops of their head.
