The requirements were that it had to be interactive: which means that, at some point, the user had to do something that would influence the plot of the animation - and it had to be obvious enough for the user that they need to do that, without any instructions.
The animation also had to contain some sort of audio. I have chosen to use the audio from the movie itself, combined with the free sounds I have found on the internet (for the peek point of the animation, which will indicate the user that "it is time" to do something).
Also, in order to indicate the moment where the user needs to interact in order to make the animation continue, the main character (Ramona) turns slightly transparent, until you hover over her and the cursor also turns into a pointer, meaning that it is time to click!
So ladies and gentlemen, I present to you:
(Sadly, the animation does not work properly on devices that have less than 1380px in width)
