Continuity mistake: In the scene where they are playing the bone-organ to escape, the Fratellis walk across the beam then climb the rocks to get to the room where the Goonies are.

A shot shows one Fratelli brother stick his hand on this post to pull himself up, but in the next shot the hand is gone and a moment later the Fratellis emerge from the water.

Continuity mistake: When Mikey takes the skull necklace off Chester Copperpot, he accidentally pulls Chester's skull off his body. When Mikey does this, the skull is still touching the body, just detached and at the wrong angle. But the next shot we see with the skull, when Brand goes to place the skull back on the body, the skull is about a foot away from the body.
