Fillmore Easter Egg - Cafeteria Characters

In the episode where Fillmore and Third are tracking down a student who can't be traced (I believe her name was Elexis) they show a shot of the cafeteria. If you look closely you can see some characters from other Disney shows. I saw two right off but I am sure there are more. I saw Speneli (I'm not sure how to spell it, the girl from recess with the hat and the leather jacket) and I saw Kim Possible (only from the back but I think it was her, long red hair, black shirt, and cargo pants). I am sure there are more but I only saw this one once. I guess channel surfing really pays off when you're sick and watching commercials for shows all day.
