This is inspired by a live action tv show that I used to watch when I was a kid in Spain. It takes place in Spain during the 30's the girl's name is Celia, and she has an awesome imagination, but she always gets in trouble, so then she gets sent to a nun's cathlic school... anyone that would watch that show would feel sorry for her.
This is when Celia pretended to drive her little brother in a Ford convertible. Then ofcourse the worse happens...
And this is just them imagening that they have to cross the atlantic ocean through a bridge, and they can't fall in because there is sharks and huge white whales.
