Τα στοιχεία της Μπλού is the Greek dub of Blue's Clues that airs in the country of Greece. Only two clips of this show are found on YouTube, both are TV bumpers for the show, and are in VHS quality. Links down below:
UPDATE (December 23, 2017): BoyInCharge55 here. I managed to find the theme song in Greek. The kids are...average sounding to me. Also, Blue's barks are not heard here.
UPDATE (May 15, 2018): Hey, it's Gabe The Sesame Street Fan from YouTube. I just wanna say that a fellow Blue's Clues fan called Blue'sClues&TheWigglesFTW TeenTitansGo!FTL found some episodes of Greek Blue's Clues. Here's the YouTube video with the links to the episodes: https://www.youtube.com/watch?v=MMbshlol44s
