Story Beats, Version (stopped counting at this point)

I realize that I haven't really put down a true list of story beats, so here they are. Things have changed, but the story is mostly the same.

-Camera fades up from black on an old, dirty sign that reads "Danger! Do not enter." There are footsteps, and a shadow quickly passes by
-Next shot, a boy (Billy) drops a box onto a ledge, obviously exhausted.
-Billy opens the box and takes out a manual.
-The first page of the manual reads: "Thank you for buying this Instant Dragon Kit. Please read all directions fully before ..."
-Billy flips the page and the second page shows a picture of a knight on the back of a dragon.
-Billy smiles.
-Billy flips the page and the third page reads: "Step one, find a well," and shows a picture of an old well.
-Billy looks up, and this is the first shot of the environment as an establishing shot. It is a grimy, old factory with a giant vat in the center. The box is resting on the edge of the vat, which the boy is looking down into.
-Billy turns to the next page which shows some of the ingredients.
-Billy begins adding ingredients to the well in a quick montage sequence. The well starts to bubble and change into different colors.
-At one point, Billy adds the wrong ingredient and the well starts turning a thick pastel orange. Billy realizes this is wrong, makes a face, and starts to scoop it back out.
-Billy gets to the second to last page in the book, which reads: "Final ingredient: WARNING, be sure to use no more than a couple drops."
-Billy carefully takes out the final ingredient, a vial of glowing pink fluid, and uncorks it.
-Suddenly, the lights flicker, and Billy looks up nervously.
-With the camera tightly framed on Billy's face, Billy adds a single drop of the final ingredient into the well.
-A shot of the well shows that nothing has happened except for a tiny ripple from the drop.
-Slightly frustrated, Billy adds in a few more drops. Again nothing happens.
-Billy pounds the side of the vat, and the vial of ingredient slips off the side of the well and into the liquid. The fluorescent lights above go completely black, leaving Billy only in the glow of the vat. Billy makes a scared face.
-The camera follows the liquid into the well beneath the liquid.
-As the vial sinks to the bottom, viscous pink liquid flows out of the bottle and starts forming into a dragon embryo.
-Cutting back, the liquid is now bubbling furiously. A dragon bursts out of the liquid and rises into the air, roaring and breathing licks of flame.
-Billy looks on in wonder, with the dragon's shape reflecting in his eyes.
-The lights suddenly click on, and the dragon makes a face.
-The next shot shows Billy and the dragon in frame. The dragon is very tiny.
-Billy looks on in wonder as the dragon lands on the edge of the well, kind of upset that he's so small.
-Billy's surprised expression slowly turns into a smile, and he puts the dragon on his shoulder. The manual's last page shows the same picture of the knight on the dragon, and the caption "Enjoy your new mighty dragon!"
-Billy walks over to the picture and touches the dragon's face, slightly disappointed.
-The dragon makes an angry face, and breathes a huge roar of flame that instantly reduces the manual to ash.
-Billy is totally surprised, but then gets a mischievous face, which the dragon mimics.
-With the dragon on his shoulder, Billy runs out of the factory.

Yes, I'm drowning in animation at this point. Someone, advice on cutting it down whilst keeping the story intact? And of course, any story critiques are greatly appreciated...
