The Allied Mom Force!!

is episode 281 of the Naruto: Shippūden anime.

Summary
Ebisu gathers the remaining personnel in Konohagakure to prepare for the eventuality of an attack, but the mothers of the Allied Mothers Force reassures him that they were ready to defend the village. Throughout the day, Konohamaru, who is intent on protecting the village, receives intel from the other children in the village about people lurking in the surrounding forests. This however, seemingly turns out to only be a travelling circus, until a group of Sumo Wrestlers attempts to attack the village. They are, however, unceremoniously defeated by the alliance of mothers and later Konohamaru who finishes them off with a Rasengan.

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.
