Draw a large circle on a sheet of paper. Make the radius of the circle at least two inches to make it easier to add Jigglypuff's appendages.
Draw four more circles on the paper, each with a diameter of one inch. Draw two small triangles as well.
Cut out all five circles and the two triangles with a pair of scissors.
Glue the four smaller circles onto the larger circle. These will be Jigglypuff's hands and feet. Attach the triangles to the top of the larger circle. These will be Jigglypuff's ears.
Draw a little swirl in between the two ears on the larger circle. This will be Jigglypuff's swirl shaped extension. You can also choose to cut the extension out of paper and glue it to Jigglypuff's face.
Draw two eyes in the center of the larger circle and color them blue. Draw a small smile near the bottom of the larger circle.
