I wonder they haven't gone after the crochet versions. Only one of t0ose had the sense not to use the actual 'Adipose' name.
but honestly, the basic shape wouldn't be hard to reproduce. It reminds me of a tooth-shaped toothfairy pillow I recently made from knitpicks, just slightly modified, and add little arms & legs.
or this one might be workable: http://myfairkatie.blogspot.com/sear...othFairyPillow
Or I bet you could search thru amigurmi patterns and find something the same basic shape.
Or grab one of the crochet patterns just to use as a template to recreate the shape in knitting. Or learn to crochet. :-)
