What are the release dates for Agatha and Tillie Episode 1 - 2006?

There seems to be some confusion. There is no known TV series or episode called "Agatha and Tillie" with a release date in 2006.

It's possible that:

* You are misremembering the name of the show or the year. Try searching for similar titles or checking your sources again.

* It's a show that was never released publicly. It could have been a pilot episode or a project that never made it to production.

Could you please double-check the information or provide more details about the show?
