In the short film, Pikachu and Pichu, before the Tower of the Unown movie a Voltorb pops up in Smearegle's artistic little hideout and says "Electrode!" Later they show every single Pokémon that lives in this hideout and there is not a single Voltorb to be seen. One thing, there is no such thing as a Voltorb who says Electrode, and another, the Voltorb vanishes.
