Does Jack-Jack have a Nemo bib on?
Just look at Jack-Jack's bib. It's go Nemo from Finding Nemo on it!
Does Jack-Jack have a Nemo bib on? Because I looked on Amazon.co.uk's version of The Incredibles on Blu-ray, and on the front cover it showed Jack-Jack having a Nemo bib on. Look at this link and look at the picture on the left-hand side of the page.
