This episode is more of an omake than a true episode. It's a silly episode as it can be told by the episode screen's style. (The writer of the episode that did Episode 101 did this one). Naruto trains in the woods and picks up more than a sweat. He gets a cute companion that thinks Naruto is his mother. Through silly and funny screens of Sakura, Tsunade, Shizune, Akamaru, Kiba, Lee and Hinata this can be sure an episode to keep you either laughing or smiling at it.
I personally thought this was one of the funniest parody episodes in the series, as I said the writer of episode 101 where they tried to see Kakashi's true face, and the other episode where Naruto tried to make Tsunade pay a debt prior, did this one. So it's guaranteed to be funny. :P
