The reason I did not put in such footage is because it would not have fit in well with the lyrics themselves, in my opinion. For example, the main line is "It's so easy to destroy and comdemn the ones you do not understand". Showing a scene of Chomper's mom nuzzling him just wouldn't seem to fit too well to this verse.
I did try to make a tribute to Chomper's parents once, but it did not work out so well.
I have all the movies.
