Tonton


 * Seiyu: Keiko Nemoto
 * Voice acting: Megan Hollingshead

is Tsunade's pet pig, often kept in the care of Shizune. She does not speak in any human language, but still manages to get her point across by whining in her own unique tone; which in the original anime sounds like "buhi" (the sound made by pigs in Japanese culture, similar to the onomatopoeia "oink" in English Dub, which is also used in the dub). It seems that Tsunade and Shizune are able to understand what Tonton is trying to say. Tonton's nose also seems adept at tracking things. Also Kakashi's summoning, Pakkun, seems to know Tonton on a casual nature suggesting they have tracked before.

In the video games Naruto: Ultimate Ninja 2, Naruto: Ultimate Ninja Heroes 2: Phantom Fortress and Naruto: Ultimate Ninja 3, Tonton is used by Shizune in "Hog Style: Tonton", which is a jutsu that throws Tonton at an opponent while spinning upward.

Tonton has yet to reappear in Part 2.
