Ibuse

is a venomous salamander. It is large enough for its summoner to stand on top of its head. When not summoned, it resides with the rest of the salamanders in Amegakure's Salamander Habitat.

Abilities
Ibuse is able to release a Poison Mist from its mouth, which is capable of making the entirety of a victim's body numb just moments after inhalation and may eventually prove fatal, although these effects can be counteracted with the correct antidote. The poison must first be generated and then stored for a total of five minutes within Ibuse's body before it can be expelled again.

Ibuse is capable of concealing itself and navigating underground. It can then resurface beneath it's enemies and swallow them, trapping them in its mouth until they have succumbed to the fatal effects of the poison. Underwater travel is also possible, through crawling quickly along the floor of any body of water.
