Visible crew/equipment: After Hook is eaten by the giant crocodile Peter shouts "Bangarang!" and the kids start yelling it as well. Look on the far right of the screen, behind and underneath the crocodile, and you can see a pair of legs in blue denim jeans just standing there. (01:59:41)
Visible crew/equipment: When the Lost Boys begin to chase Peter around their hideout there is a shot that starts high up in the trees and moves down as it closes in on Peter running from the kids. As the shot passes a support beam attached to the track that Rufio's sail-ship runs on you can see the camera's shadow cast on the support. (00:52:22)
Visible crew/equipment: When Peter first arrives at Neverland we see Smee taking Captain Hook's hook to the ship. When the camera pans underneath the ship's sails to reveal the giant human skeleton attached to the prow you can see a metal walkway at the top of the screen, behind the sails, and the legs of some crew members stood on it.

Answer: Neverland very much runs on "If you believe, it will happen" which is what Tink means during the meal when she says "If you don't imagine yourself as Peter Pan you won't be Peter Pan." So by the rules of Neverland, as soon as Peter believed it was real it was then real. The dinner was trying to teach him to believe as, in Neverland, if you don't believe it then it won't happen.
