"Littlerock" reminded me of when I was 2 and visiting a German playground. Met some kids. Had the best conversation ever. They spoke German, I responded in Romanian. The only slight issue - tiny niggle - with matching this to "Littlerock" is that the characters are totally uninclined to use the dictionary they have (!!!) even during heart-wrenching crying conversation, which seems a bit impractical, if sentimental.
