Sanshōuo (山椒魚, Sanshōuo, Literally meaning: Salamander) is a puppet, originally created by Sasori and passed onto Kankurō. Unlike Kankurō's other puppets, Sanshōuo stays true to its name and somewhat resembles an actual salamander. Sanshōuo is a puppet that has high defensive power.
It has a frill that swings up to defend against attacks from the front as well as the tail being able to tuck up to reach the frill and guard the rear followed by an iron cloak immediately covering all sides, and a hollow body. Kankurō and up to two other people can take cover in to defend against attacks coming from other directions. Its weak point is the side joint of the frill, which when struck will knock the shield off, rendering it defenceless. Kankurō later repaired it after it was dismantled by Sasori.
