Okay, do not be alarmed, they aren’t speaking in some weird made-up Croodacious language or anything.  It’s just Faf Larage rapping in French, so enjoy!  This video has the English subtitles, so you can read along, too.  I gotta say, it’s a bit quirky and sure, it’s probably not appealing to everyone, but it’s definitely something we don’t get a lot of for animated films: dancing numbers by children in a rap video.
