Name of the boss toad?
That big toad is a summon

Gamabunta is the boss of the toads that are summoned. He is huge (about 100 meters high) and is summoned for battles with the biggest of enemies. Naruto can only summon him with his demon fox chakra. Without it, Naruto can only call upon some of Gamabunta's smallest children. Gamabunta is first seen in the premiere of the series, where he and the Fourth Hokage face off against the Demon fox. He is not given a speaking role until he is first summoned by Naruto in the month long training session with Jiraiya. Jiraiya pushed him over a cliff in order to induce life-threatening fear in Naruto so that the Demon fox chakra could come out, but never expected Naruto to summon Gamabunta. Given that Gamabunta wasn't happy about appearing at the bottom of a canyon, Jiraiya quickly fled.
