First, I should recall the basics about Dora the Explorer. It's an educational children's show that originally aired in the US and was dubbed into many languages. The character Dora is a young girl who goes on adventures, teaching Spanish and problem-solving. The original dubbing might have been in Spanish, but many other countries have their own versions.

Sites like the Fandub Database track unofficial projects across different languages.
