Streaming on Netflix. . .
For those who don't know it, All four seasons are streaming on Netflix. The order though, differs from the airing order listed on IMDB.
Also, IMHO The voice actors should be listed first on both Netflix and IMDB but they aren't. My reasoning is that fans/viewers are more likely to know or want to know who the voice is behind such-n-such a character before knowing who the puppeteer or physical actor might be.
