Guidepost of the Camellia (椿の道標, Tsubaki no Dōhyō) is episode 108 of the Naruto: Shippūden anime.
Naruto and Guren helped each other escape from the hungry mini-Three-Tails as Rinji's men attacked Lee's group. Yūkimaru and Kakashi devised a plan to track down the Three-Tails using the boy's power so that they could then get Naruto and Guren out. After Naruto and Guren managed to escape from an illusion-making fog, Naruto began to realise that Guren actually had good intentions. Yūkimaru then played the song his mother had taught him right above where the Three-Tails was submerged, and Kakashi made a crack in the beast's barrier. Naruto and Guren heard the tune and blasted their way out.
