Pokémon "It's New Year's Eve! Pocket Monsters Encore" (1997 Unaired Episode)

Scheduled to air on the morning of December 31, 1997 in Japan, was a one-hour Pokémon New Year's Special. The title (which, unlike other Pokémon episodes is written in kanji) was 大晦日だよ！　ポケットモンスターアンコール, roughly translated to "It's New Year's Eve! Pocket Monsters Encore". It is believed by many to be the intended 40th episode of the anime, although these claims have been quashed by a booklet included with the Laserdisc release of Mewtwo Strikes Back!
