Тонтон

Tonton is Tsunade's ninja pig, often kept in the care of Shizune. She is always seen wearing a pearl collar and a dark red jacket.

Tonton's sense of smell is noted to be even finer than that of a ninja dog. She has reportedly smelled debt collectors coming and saved Tsunade from them countless time. She was also able to direct Shizune, Jiraiya, and Naruto to Tsunade's location after she was locked in battle. Also, despite her small size, she is strong enough to carry several crates at least as large as her.

In the anime, Tonton once performed a Transformation Technique to appear as Tsunade. However, while doing so, she was still unable to speak.
