Udon Ise

Udon (ウドン, Udon) is the friend of Konohamaru and Moegi. He is in the Genin-team led by Ebisu. He seems to have a perpetually runny nose and seems to be very sleepy. Udon states many times that he loves math, as he is usually seen writing math problems during class. Udon idolizes Sasuke Uchiha, stating that if he was lucky enough he would be just like Sasuke. "Udon" is also a type of Japanese noodle.

Part I
Chunin Exams Konohamaru makes his second appearance during the beginning of the Chunin Exam arc where he and his classmates try to sneak up on Naruto, hidden in a stone like box. However they are quickly discovered. Later on they get into a quarrel with Sakura, and then again with the Sand Siblings, as Konohamaru bumps into Kankuro, only to be saved by Sasuke.

Fillers
Konohamaru's appearance in the fillers is during a mission for which the Konoha Genin have to act as leaders to Ninja Academy students' squads. Konohamaru, Moegi and Udon are assigned to Naruto. When Naruto loses his team in the forest Konohamaru and Moegi try to use the map, but the same thing happens. After Udon tries and fails because the compass is not pointing correctly (due to the magnetic force of the forest), he faints due to the compass' spinning arrow. At sunset they are attacked by ninjas (disguised senseis of the academy, along with Shikamaru), Naruto uses the Sexy Jutsu to confuse the ninjas. This doesn't work, but Konohamaru, Moegi and Udon use it at same time and have more success using Pudding Pudding Technnique. However, Shikamaru strikes them with part of a tree's trunk because he thinks they are fools.

Gaara Retrieval arc
After the timeskip, the Konohamaru Corps have become a Genin team under Ebisu. In the anime, Konohamaru and his team were given the same mission as Naruto's team were when they first became Genin (the runaway cat). Konohamaru states that he will become the seventh Hokage and that Naruto would be the sixth. Konohamaru's scarf is even longer post-timeskip, stretching at least several feet beyond his neck. When Naruto returns after his 3 years of training he introduces himself, by showing off his new and improved Sexy Jutsu, only to be told by Naruto that they are no longer children and should not use such techniques. Naruto then reveals that he had improved it himself, and is almost about to use it, when he is smacked around by Sakura, in turn scaring Konohamaru and his friends.

Post Hidan and Kakuzu arc
Konohamaru makes his next appearance after the defeat of Hidan and Kakuzu, where he demonstrates that he has been able to learn the shadow clone technique, albeit only with a single clone (In anime along with Udon and Moegi). He continues to add the sexy technique to it, first creating two naked women, which receives a positive response from Naruto but Sakura beats him up for,(In Anime Sakura was about him up but it turned out Moegi beat him up) and then two naked males, looking like Sasuke and Sai, this time receiving a positive response from Sakura (who later tries to cover it up) for which Naruto beats him up (In the anime this part is removed).
