-TOAD SUMMON SKILLS-
Naruto was first taught how to use the Summoning Technique by Jiraiya. After allowing Naruto to sign the Summoning Contract with the toads of Myōbokuzan, Jiraiya took Naruto through the execution of the technique in order to provide Naruto with allies in future battles. Additionally, Jiraiya's other motivation to teaching Naruto how to summon, was in order to help Naruto to realize, and take advantage of, the Nine-Tails' chakra reserves. The type of toads that Naruto can summon at any time is proportional to his chakra and skill, as when he first started out he could only summon tadpoles. At first, Naruto would have a hard time getting any specific toad, as he would summon either Gamakichi or Gamatatsu. But when he used the Nine-Tails' chakra, or when he is truly motivated, Naruto was able to summon the toad boss, Gamabunta.
