The Summoning Technique allows the user to transport a creature with which a contract has been made to themselves. In Gamakichi's case, it is a toad from Mount Myoboku. To summon, one must apply blood to the palm, form five hand seals, and press the hand to a surface.
Medium-sized Gamakichi is no longer the little toad from their first meeting, but he is also not yet the giant from the times of the Fourth World War. His height is now comparable to Naruto's, and the latter can stand on his head, though Gamabunta still remains enormous to him. During this period, Gamakichi looks like a toad with orange skin and purple markings around his eyes and mouth. He no longer wears the children's jacket, but he has not yet acquired the cigarette and giant sword, as in later years. He has noticeably grown in strength and can now serve not only a supporting role, but also as a true combat unit.
