gingerbread man arm

Using the latest Blender: I followed the instructions for extruding an arm- select the vertices and extrude them, but all I get is extruded vertices without faces.

I’m not sure if the instructions are obsolete or something. I seem to remember trying this out in an older version without a problem. Am I doing this wrong?

When you extrude select “Extrude Region” not “Vertices”.
