Suppose a preview video of Turtle Talk on the Dream showed a little girl gabbing it up with Crush, having the time of her life. And then when the Dream finally set sail, not only did we not have an interactive Crush in AP, but we had no Crush, period.
You could say, “Well, that video was obviously fantasy. Everybody knows that turtles can’t talk.”
No, turtles can’t talk, but we can use technology to approximate a fully-interactive virtual puppet of a talking turtle.
That is precisely what Disney sells - their creative and innovative use of technology to make fantastical things seem more real. Not 100% real, of course, but closer to reality than we would normally expect, which surprises and delights us. It’s why we pay exorbitant sums for these vacations.
Stuff like that is Imagineering’s stock-in-trade. It’s why they exist. So I don’t think it’s at all unreasonable to watch that video and walk away with the clear impression that there was some sort of shrinking/enlarging gimmick in store for dessert.
I mean - why even show the cupcake getting big? You just saw Ant-Man enlarge two seconds ago. Why immediately repeat the schtick with the dessert that was just handed to the little girl, and give her agency to make the dessert bigger, if there’s absolutely nothing in that vein that’s part of the actual dessert experience?
I mean, unless there is something cool that happens, and nobody on the media preview has spilled the beans.
