What episode does naruto and sakura go to a festival?

It's not an episode, it's Omake! means are short extras that appear ar the end of the certain episode within the Naruto: Shippuden plot. Anywho, it appeared at the end of episode 129 (Infiltrate! The Village Hidden In The Rain) as an extra, the short is called "festival" (duh!) and just skip to the end, minute 22:04 to watch the short! :)
