Continuity mistake: When Joey is being carried by the dragon, they are shown flying over the river. The following shot shows them continuing to fly forwards, but when the dragon lets go of Joey, he is shown falling over land and the river can no longer be seen. (00:03:18)
Revealing mistake: When Joey lands on the dragon's nest, he sits up and yells, "You're lucky you're up there, pal," to the dragon. When he sits up, a piece of hay in the nest can be seen layered over the bottom of his jacket, making it appear as if the piece of hay is floating. (00:03:28)
Continuity mistake: When Joey finds the treasure chest, in the shot of him saying "I'm rich, baby," he raises his forearms so that they are level with his shoulders. But in the next shot, his arms are raised in the air. (00:13:57)
Continuity mistake: When the treasure chest opens, Joey opens his mouth with a shocked expression on his face. Then there is a close-up on his face, where he is now smiling. (00:14:37)
Continuity mistake: A map emerges from the treasure chest and wraps itself around Joey. The map has stains on it, but when it cuts to a closer shot of Joey, the stains on the map have changed position. (00:14:48)
Audio problem: When Joey is standing under the waterfall to cool off, he is heard sighing, but his mouth doesn’t move. (00:15:11)
