Foster’s Home for Imaginary Friends is going away 🙁 And while it’s always sad to see a beloved toon move on, at least we can do it in style! Cartoon Network celebrates the final episodes of the animated series with a six-hour Foster’s marathon of five episodes, including the series finale, Goodbye to Bloo. The marathon airs this Sunday, May 3rd, from 1 to 7pm. The toon debuted on Cartoon Network on August 13th, 2004, so it had a nice long run. Let’s give it a good home here at ToonBarn!
