I don't know about you, but the first thing that enters my mind every time I see Han cut open his tauntaun to warm Luke with its innards is, "Mmmm, that looks cozy."
The good folks over at Thinkgeek.com have gone ahead and taken it one step further. Now your young one can sleep "in the belly of the beast"... literally experiencing the warmth (and smell) of the inside of a tauntaun*.
