So far, two of the Blue's Clues hosted outside the US: Kevin of the UK and Duarte of Portugal. There was definitely a Korean host as proven in Behind the Clues: 10 Years With Blue, but no episodes have surfaced of that version. There was a pilot clip of Pistas De Blue in Latin America with a different host, but no info has surfaced on its origin. There are even rumors that there may be an Arab host, but there is barely anything to go on. Outside of that, all other language versions are dubbed with the US version.
