The leaf creatures speak with German accents. The story the series is based upon, Rapunzel, was recorder by the German story collectors known as the Brothers Grimm.
The leaf creatures speak with German accents but the "German" words they say (like "kloopenhogun" and "freinfloofen") are gibberish.
This is the first time Pascal is ever referred to as a chameleon in the series. In the movie Tangled (2010), as Eugene and Rapunzel are walking through the tunnels under the Snuggly Ducking, Eugene calls Pascal a frog, and Rapunzel replies that Pascal is a chameleon.
