The Allied Mom Force!!

is episode 281 of the Naruto: Shippūden anime.

Summary
Ebisu-sensei gathers the remaining personnel in Konohagure to prepare for the eventuality of an attack, but the women of the Allied Mom Forces reassures him that they were ready to defend the village of Konoha. Throughout the day, Konohamaru, who is intent on protecting the village, receives information from the kids in the village that there are some threats to the village in the surrounding forests. This however, seemingly turns out to only be a travelling circus troupe, until a group of Sumo Wrestlers attempts to conquer the seemingly undefended village. They are, however, undeniably defeated by the alliance of mothers and later Konohamaru who finishes them off with a Rasengan thus making them run away in fear. In the end Konohamaru managed to show the other children, who ridiculed him, the Will of Fire.

Trivia

 * Konohamaru stated he and Naruto were the only living people that know Rasengan, however, unknown to him, Kakashi knows this technique as well.
 * When the Allied Mothers Force confronted the Sumo Wrestlers, one of the mothers beared a striking resemblance to Tenten. Whether or not she is Tenten's mother is unknown.
