Naruto 151

Naruto has difficulty learning the move, which involves using Chakra to spin the water inside the balloon and burst it. Jiraiya mentions that it is among the hardest to learn, taking even the 4th Hokage, who invented it, 3 years to fully perfect it. Naruto is unable to figure out the secret behind it and Jiraiya refuses to tell him, insisting that figuring it out himself is the only way to use it right. Naruto then sees a cat toying with a balloon and after watching it, gains inspiration. Jiraiya is woken up by water in his face and Naruto standing over him with the remains of a burst balloon in his hand.
