Pokémon "Pocket Monsters, Winter Special!" (lost unaired "clip show" episode of anime series; 1998)
Set to air on January 6th, 1998, in Japan was a clip show called "Pocket Monsters, Winter Special!" (ポケットモンスター・冬のスペシャル!). This episode would have aired right after "Snow Way Out!". It is unknown how long the episode would have been, though it would have summed up episodes until "Holiday Hi-Jynx" (which itself never aired in some countries due to Jynx looking like an African-American stereotype). The episode was cancelled after the "Dennō Senshi Porygon" incident, which ended up giving Pokémon a four-month hiatus. A different version of this special that showed "Holiday Hi-Jynx" and "Snow Way Out" later aired on October 5, 1998, and became an hour long. Though the clip show version never aired.
This episode shares the reputation of being one of five Pokémon episodes to have never been released, the other four being "It's New Year's Eve! Pocket Monsters Encore" (a 1997 episode that was ultimately cancelled due to the fallout following the infamous "Pokémon seizure incident"), "Rocket-dan VS Plasma-dan!" (a two part 2011 episode that was cancelled shortly after the devastating Tohoku earthquake and tsunami) and "Battle of the Quaking Island! Barboach VS Whiscash!!" (a 2004 episode that was cancelled as a result of the Chuetsu earthquake of the same year).
