The Mover Vigoroth cry glitch is a sound sample selection oversight in the Japanese version of Pokémon Emerald.
As long as the player hasn't entered their room after starting a new game, they can talk to the truck-unloading Pokémon in their home. In Pokémon Ruby and Sapphire, they are a pair of Machamp, which were visually changed to Vigoroths in Pokémon Emerald, but their cry wasn't until the release of the international versions of the game.
Game versions
Possibly due to confusion with other Pokémon games which received bugfix updates (especially the three English versions of Ruby), this glitch is sometimes misattributed to an "early version" of the game; however Pokémon Emerald was only released in one version (correctly numbered as 1.0) for each of the six monolingual releases, making the claim true only literally - the Japanese version having launched first.
