If they absolutely have to be in the "extras" menu.. open a terminal:
as root
Code:
cp /usr/share/applications/hildon/ooo.desktop /usr/share/applications/hildon/mynewapp.desktop
vi /usr/share/applications/hildon/mynewapp.desktop
Change to something like
Code:
[Desktop Entry]
Encoding=UTF-8
Name=UberSoftware
GenericName=UberSoftware
Exec=debbie application
Icon=<find an icon, or leave it to be Open Office's>

Thanks, Fatalsaint. I got the app into my custom menu and when I click on the app it opens in Hildon window(sweeeet!!!). Now can you please write out the path where the Icon for Openoffice.png is so I can add my new Debian apps icon into that path. I will show a screenshot afterwards.
