Puffy and Stringy stool after eating shirataki noodles?

The other day I had a bowel movement and noticed that it looked different than I've ever seen in my life.  My bowels looked like I basically had not digested the Shirataki noodles I'd eaten and it was still in the noodles/shape form except brown and puffy where it still looked like feces, just not how feces normally looks.  I didn't see any blood or any white coloration but was still concerned.  Can't seem to find anything online about this.  Anyone heard of this?  Concerned me since I've never seen this before in my life.

Hi,
Do you still have that symptom?
Was it foul smelling?
Any Abdominal pain?

Absolutely normal.
This happens to me as well whenever I eat a Large quantity of the Shirataki noodles (and especially if I don't mix/consume much additional other Solid food with it)
Shirataki noodles are an EXTREMELY high NON-digestible fiber (hence why it's only 0-20 calories for a whole package! And why it comes "out", pretty much the same as it went "in"!hehe
Plus some "puffiness" due to the high water absorption from the fiber-ous content.
Hope this helps and continue enjoying your noodles! :D
