Diglett was introduced in the first generation of Pokemon games, released in Japan in 1996 as Pokemon Red and Green. As a Ground-type Pokemon that lives underground with only its head visible, its cry was created as a short synthesized sound suited to the Game Boy hardware of the era. That same cry style carried through later remakes and handheld entries, so generations of players learned it by heart. Online, fans share the isolated cry for soundboards, fan games and nostalgic edits.
