Since I don't have detailed knowledge of this specific graphic novel, it could be about a variety of things. It might center around the different attractions in the fun house like the hall of mirrors, the spinning tunnels, etc. and how these features impact the characters. Maybe there are characters who get lost in the fun house and their journey to find their way out, all while facing various challenges and meeting other characters along the way. It could also explore themes like friendship, courage, or self - discovery within the context of this wacky fun house setting.
I'm not sure exactly as I haven't read it. But generally, a graphic novel often has a unique story. It might be about the adventures that happen inside a fun house, perhaps with some interesting characters and a plot full of twists and turns.
