The Clone Wars: Clone Cadets

We jump from Star Wars: The Clone Wars theatrical feature released in 2008 all the way to the Season 3 premiere which aired in 2010. This episode takes place on Kamino where we get a glimpse into the training process of the clones. Sometimes the clones really, really suck at the one thing they're literally created to do. In "Clone Cadets" we see what happens when a bunch of crappy clones get grouped together and how the higher-ups deal when bad batches of clones are cooked.
