After three unsuccessful submissions over two years, we finally made our way into Yahoo on our forth submission: http://dir.yahoo.com/Recreation/Toys/To ... er_Soaker/
I'd suggest submitting your website if you think you could stand aside the sites listed. Just remember, keep submitting, but don't submit too often or they'll never add you (from what I hear). I submitted once every 6 or so months, and after two years I finally made it.
Thanks to the great folks at Yahoo! B)
