Well, I know it is really important to froogle to have what you feed them match what is on your site. So if you don't have descriptions on your site, and you submit descriptions to them, they might get upset if they find out.
I assume you are talking about the site in your sig. I looked real quick and saw that your individual products don't seem to have their own page and no place for the description; is this where the problem is coming from?
You might want to modify your cart (I realize this is not going to be an easy job) so that each product has it's own page and description. Or at least modify the current page so that each product has its own description. Both of these will help with your SERPs, too.
It has been my experience (of couse this was in Froogle's earlier days) that the froogle team was very responsive to questions from merchants. You might try shooting them your question. There is a "contact us" link at the bottom of
this page.
