If im not mistaken, he's the one who can summon Fukurokumaru Cat .. But in the anime, Fuku Cat is somewhat made of metal .. It is the episode where the Pains and Konan invaded the konoha while Naruto is having training in Mount Myoboku ..

Yes2, but the metal Fuku Cat he used it to capture one of Chikushodo's Summon, i forgot if its the Rhino or the Eight Span Bird .. Then he has this another one, the China Man holding Gold Ingots, while the interrogated one is being strangled by wires ..
