Yadoking no Ichinichi

ヤドキングのいちにち

Synopsis

It consists of nothing but Pokémon-speak--similar to the mini-movies that air with each theatrical movie. It's a short special based on life of the Pokémon Slowking. It was never released outside of Japan and Greece, due to it only being a few minutes long. But it was officially dubbed in Russian. (Source: Bulbapedia and Graffitti studio)
