Enter the following codes for Konohamuru at the top of the academy by assuming the touch screen is divided into a 4x3 grid, numbered as follows (instead of using the "Summoning Sheet" from Shonen Jump magazine). Note: He does not appear there until the game has been completed.

[1] [2] [3] [4]
[5] [6] [7] [8]
[9] [10] [11] [12]

Then, quickly tap the indicated grid area. The numbers "1" through "4" will appear on the top screen to indicate that the first through fourth numbers have been detected; this is not the "grid" number, but simply to confirm that your tap has been detected.

Find all "Ripped Scrolls" and take to the Hokage's Basement

If you need to practice or gain experience first,go to the beginning of the Garra's Pursuit level or the Forest Of Death to level up. You can get the Ninja Whistle in the Hokage's Basement on about the fifth to seventh secret scroll. It automatically summons enemies for you.

After you battle Temari and Gaara at the Chunin exams, you will face Kankuro in the Gaara's Pursuit level. If you can memorize their moves, you should know how to defeat them. However, if you are lower than level 40 for each character, train them to that level or higher to have a successful victory.
