One Piece Omake

One Piece Omake, also known as Mugiwara Theatre, are short manga chapters originally published in the One Piece log books and databooks. So far, five of them (Report Time through Monster Time) have been animated and aired with a set of five "Recap" episodes aired during the Enies Lobby arc. The first two Omake shorts, Orchestra of the Sea and 4-Panel Comic Strips, and all those following Monster Time have not been adapted into the anime yet. There have been 15 in total.
