How to add xeyes to the taskbar

Hoping my question is not regarded as silly, I would like to know how, if possible, I can attach the xeyes utility to the task bar. I do not simply want an icon on the task bar for launching xeyes, but rather have the animated eyes appear on the taskbar and not in a separate window. I'm fairly sure I had it this way on a debian distribution about 10 years ago. I am currently running squeeze and my desktop environment is GNOME 2.30.2.
