Blue's Clues (partially found KBS Korean adaptation of Nickelodeon TV series; 2000)
For those of you who don't know, Blue's Clues is an American children's television show that premiered on Nickelodeon in 1996 to 2006. To make it short, It's about a dog named Blue and someone named Steve or Joe (or Kevin if you are from the UK or Ireland). There is a Korean Adaptation of this show.
There are apparently two Korean versions of this show, one under the title "Blue Puzzle" (수수께끼 블루) which aired on KBS2, and another under the name "블루스 클루스" (a translation of the English name) which aired on Nickelodeon. Not much is known about the KBS2 version, for only a brief clip was seen during the 2006 special, Behind the Clues: 10 Years With Blue.
One thing that is known is that Steve is replaced by a character with the name "HyunShup Shin", which the same thing was done in the U.K. English dub, where Steve is replaced by Kevin. So far there are only two clips of footage of it online. Blue's Clues can still be seen on the Korean Nickelodeon website, but the Nickelodeon Korean dub is just a dub of the American English dub.
A user named Fenoman found some screenshots of the Korean dub on a Korean blog post about fixing a VHS tape, along with a clip from Maggie and the Ferocious Beast. Proof is right here .
