"The Pani Poni Dash! OVA" is an original video animation anime that was released on the complete set of the anime series on April 15, 2009 in Japan. It was never licensed and dubbed in english.
Several of the students at the school have recently failed a major exam, and are going to be required to retake it. But, they can get out of it, if they win a game of Kick the Can, which for the purposes of plot is the same as Capture the Flag. Becky leads the defending team while Rei heads the attacking students. Hijinks ensue, betrayals occur, and the ending is as deadpanned as always.
