Berryz's most childlike girl : There was a Momoko Call. The girls waited and answered together, "Momoko!" And they won.

I'm not sure about this game they played. They probably had to shout out their answers at the same time and see which team get more matches.
And they performed 2 songs; Munasawagi Scarlet and Waracchaou. It went like this; Munasuka -> Waracchao -> Munasuka.
