First, make a 8-segment can. Cut off the top. Extend the flaps. Bend each flap as shown in the video below. Cut the legs into a pointy shape. Cut the arms as best you can. Cut out the eyes as shown in the video.

I find it easiest to make the eyes by first cutting the the top of the panel into a rounded shape. Then, cut down the middle. Then cut the eyeholes. Then cut the eyes into a rounded shape, and take some material from the center edge below the eye to make the stalks. Then bend all that into a shape you find aesthetically pleasing.

I copied this design from this guy.
