Tonton

is Tsunade's pet pig, often kept in the care of Shizune.

Personality
Tonton does not speak in any human language, but still manages to get her point across by whining in her own unique tone (a "buhi" or "oink" depending on the language). 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, such so that Pakkun has some familiarity with her.

Appearance
Tonton is of a light pinkish colour, much like any other pig. Her cheeks blush in a darker shade of the same pink as her skin. She is always seen wearing a pearl collar and a red jumper.

Abilities
The only official ability Tonton has been shown to have is a keen sense of smell. In the video games however, Tonton has shown herself to be a partner to Shizune in some of her jutsu, similar to Kiba and Akamaru. In the anime, Tonton performed a Transformation Technique, appearing as Tsunade (although she did not speak). It could be that Shizune performed the technique on her, just like she does in the video games.

Trivia

 * In the video games Naruto: Ultimate Ninja 2, Naruto: Ultimate Ninja Heroes 2: Phantom Fortress, Naruto: Ultimate Ninja 3, Naruto Shippūden: Ultimate Ninja 4 and Naruto Shippūden: Ultimate Ninja 5, Tonton is used by Shizune in "Hog Style: Tonton", which is a jutsu that throws Tonton at an opponent while spinning upward. In Naruto: Ultimate Ninja 4, Tonton is used as a partner to Shizune, helping her out in her Ultimate Jutsu by transforming into an image of Shizune and attacking the enemy to distract them from Shizune's main attack. In Shizune's "Great Cross Slash", Tonton butts the enemy in the stomach to knock the enemy back for Shizune's main attack.
 * In Naruto: Path of the Ninja 2, Tonton could be summoned to break rocks in the players path.
 * After Tsunade awoke from her coma from chakra overuse in the battle against Akatsuki, she made it look almost desiring to eat Tonton in the lack of food to replenish her chakra, much to Tonton and Shizune's panic.
