I'm normally not big on customization, but Moosebot has come up with an incredibly simple way to make articulated short legs
. Take a pair of minifig legs and carefully cut off the legs just below the rounded part. Now here's the incredibly clever bit - the holes on what was originally the fig's rear end become connector to attach feet. You could use yellow 1x1 plates as in the image shown to be bare feet, or use plates that match the legs, or even the 1x1 plate with tooth to be pointed boots. What a great way to make hobbits, dwarfs, kids, etc, without having to use the static stubbies.
