To help promote the upcoming One Piece: Episode of Skypiea television special, Mayumi Tanaka and Kappei Yamaguchi put on motion capture devices and went full virtual with their One Piece characters. From ANN:
@ANN:
Some of the various exercises and goofy antics the two get into in the video include posing like their characters, dancing, acting like a manzai comedy duo, playing rock-paper-scissors, balancing on one leg, doing a "kancho" (think Kakashi's "One Thousand Years of Death" move from Naruto), acting out scenes from the One Piece anime, and playing charades. In the final charade about "Who" is "Doing What" "Where," Tanaka correctly guesses "In Skypeia, Vivi is imitating a Celestial Dragon."
Goofy stuff but quite funny:
