I'd like these. And yeah, an aquatic episode would be cool. Since they're going to Europe, a Slavic myth seems appropriate. A Rusalka or a Vodianoi would be good for the aquatic episode. Around Germany, there are Nachtkrapp (giant, nocturnal raven-like birds that are used to scare children into going to bed), Ruebezahl, Erdhenne, Aufhocker, etc. Europe is rich with opportunites.
