Gamatatsu

is one of Gamabunta's children and Gamakichi's younger brother who has a fixation with snacks.

Personality
Gamatatsu has shown that he'd choose snacks over someone's life. When Naruto is injured while fighting with Kabuto Yakushi, he replies, "Hey Gamakichi, do we have to wait for the kid to croak till we get snacks, cuz' I'm getting hungry". Although in the filler arcs Gamatatsu showed that he does care about Naruto's life as he was ready to rescue him before Gamakichi talked him out of it. It should be noted that Gamatatsu appears to be the most subservient and loyal of the main frog summons as he was willing to serve Naruto before Gamakichi brought up the snack remark. While being naive and childishly stupid, he does sometimes make use of his natural curiosity to help Naruto solve puzzles (like the mystery of the Ghost Warrior in the filler arcs). He is always hungry and asking his summoner for snacks, and often gets mixed up in unusual predicaments which he counts on his "big brother Gamakichi" to get him out of. In the english dub, his voice is jocularly high and he is usually used for comic relief when he is summoned. He also openly refers to Gamabunta as "daddy", which the older toad either chooses to ignore or simply doesn't mind. Since Gamakichi appeared in the Shippuden sagas, it is possible that Gamatatatsu might do the sam as well. Whether he has gotten stronger and/or smarter has yet to be seen.

Search for Tsunade
Gamatatsu was accidentally summoned by Naruto Uzumaki in an attempt to compensate for Jiraiya's failed summoning. He was summoned again with Gamakichi as well by Naruto during the Noroimusha and Sea Country arcs for a scouting mission. As a summon, he seems like the antithesis of his older brother Gamakichi, being rather dull and humorously lethargic when compared to his fast-paced and smart-allec-y brother. Gamatatsu also seems to lack a sense of danger. When Orochimaru summoned Manda, Gamatatsu was too busy saying hello to his father to notice that the giant snake was staring at him. The young toad did not seem frightened in the least until Gamakichi told him to run. However, this fearlessness may also have been due to his titanic and overprotective father's presence.

Land of Birds
Gamatatsu makes a short appearance in the Land of Birds arc when Gamakichi and Naruto need him. Despite Naruto thinking he will be helpless, Gamatatsu using his curiosity finds a kite as a clue about how can the Cursed Warrior fly. Later, he goes down a dark tunnel with Naruto and Gamakichi and gets caught by the Daimyo and the guards.
