Cush at the Library (lost shorts from treehousetv.com)

I remember when I was 4-6 years old I used to go on treehousetv.com a lot. It was completely different. They used to have these exclusive shorts in their video section of the site that involved Cush (Tansy & Roseabelle's purple teddy-bear type creature from "Treetown") going to a real library and talking with a librarian (refered to as "Librarian Lady") a lot. When they revamped themselves at one point, those shorts were taken off the website. Does anyone know anything about these and how we can find them? Thanks so much.
