Back from the void, at least for a moment, a thought about the last (and only for now) news on Funtasia: two movies in addition of the Tv show.

The names are (Filly) Star and Butterfly.
That could explain in part the long delay, they are like a work of five episodes, a quarter for a season.
Of course, this can't be the only reason why we are still waiting (but this is another thing).
There are two question now: what is the movie which Dracco gave the synopsys in the last MiPCom (that explain Wranglum and its henchmen, or henchfilly as you like), and is possible that some promos cointain images from the movies, instead from the show only?
I have some idea that the scenes where Battiwig hold Wranglum and they fall in the chest could be from one of the movies.
