Soon after his training begins, Naruto finds himself unable to make any progress. After asking Jiraiya for tips, Naruto decides he will master the jutsu in three days. Jiraiya doubts the likelihood that Naruto will live up this promise, explaining that the Rasengan was developed by the Fourth Hokage in a duration of three years. He then goes on to explain that popping the balloon is only one of three steps, and leaves Naruto to resume his training.Naruto soon discovers that popping the balloon is easier if he uses both of his hands after observing a cat, and progresses to the second step.
