Giant Snake-Tailed Chameleon

A large chimera-like chameleon with snake for a tail, this summon has a number of body piercings and Rinnegan, implying it is being controlled by Pain. It is summoned during Pain's fight with Jiraiya, swallowing Pain and then turning invisible to protect him and conceal his current location. After Jiraiya summons Shima and Fukasaku; Shima is able to use a creature detection jutsu, Fighting Tongue Bind, to not only detect but also restrain the chameleon, before excreting a corrosive liquid along her tongue's length to disable its camouflage. Fukasaku then proceeds to conduct Fighting Tongue Slash in order to slice the creature in half seemingly killing it. In the anime however, the chameleon is re-summoned during the Invasion of Pain.
