If these images don't look familiar.....then you need to re-watch The Empire Strikes Back ASAP. Something about Luke and Han on Hoth and Luke gets hurt and needs to be kept warm......so Han slices open a dead Tauntaun with a light saber (hence the zipper pull! Detail, YES!) and shoves Luke inside to save his life. You too can be saved by a Tauntaun! The head serves as a pillow and there's an intestine pattern printed on the inside! Sadly, it's for indoor use only. Found at ThinkGeek.com.
