I remember making these when I was little and loved watching them grow. Bubble was given this one as a kit from her Grandparents and seems to be equally as captivated by the growing 'hair'. They are also very easy to make using pantyhose; cut one of the legs half way down and fill with either sawdust or potting mix until you have the size you want. Then lift the top of the pantyhose up so you can sprinkle grass/bird seeds along the surface of the sawdust/soil underneath the stocking. Tie it off and water it very well, then decorate with googly eyes/textas etc... if you want to. Water well a few times a day (dont let it dry out) and you should see grass growing within the week.
