Continuity: In the scene where the bad guys pick up Chunk, the mole on his face keeps switching sides. (Time)

Revealing: When all of the Goonie kids run upstairs to the attic, they rush past the camera, and you can see the image wobble slightly, as if one of them jostled the cameraman.

Continuity: When Mouth returns downstairs with Rosalita and Mikey's mom, Chunk already has the statue he broke turned away so no one will see, in the next shot he turns the statue away from everyone's view. (Time)

Revealing: When Data puts his tape in the stereo he shuts the thing then the 007 music plays. He doesn't ever push play.

Factual error: As Stef is stepping down the fireplace, you can see that her Nike swooshes are drawn on her shoes. Nike never made shoes like that. Converse made them for a couple years in the 80's. (Time)

Factual error: When the boy flattens the tires on Branden's bike, all he does to let the air out is take the valve caps off. There's actually a valve in the valve stem that needs to be depressed to let the air out. The cap is just there to keep dirt out of the valve, simply taking it off wouldn't let the air out.

Continuity: When The Goonies are all escaping from the ship towards the end, Stef punches Mama Fratelli in the face and in the background you can see some of the kids jumping. It then cuts to a long shot of the ship, and the same kids are seen jumping off for a second time.

Revealing: When Francis Fratelli is trying to pick up the gun as the Goonies are escaping from the organ, you can see the rocks shaking each time he drops the gun on the ground.

Other: When Mouth is examining the coins in the well scene, if you look closely he keeps on dropping the same coin in his hand then picking it up to examine it again. Also note that the penny he first examines is practically the size of a half dollar coin. (Time)

Continuity: When Mikey punches through the boards leading into the room with the treasure, you can see light coming through the opening. This could not be possible since there's a door on top of the opening that should block out any light. (Time)

Other: In the Summer Place scene, after Mama Fratelli sets down four glasses of "colored" water for the boys to drink. The next camera angle shows Mouth wiggling his glass in the air as he retorts, "We're supposed to drink this?", Mama snaps back, "It's wet isn't it? Drink it." If you look closely for 2 seconds you can see Corey Feldman is trying very hard to not smirk at this line, while struggling to stay in-character, as Mikey and Data say their next lines.

Continuity: In the scene when Troy is going into the bathroom you can see the back of the magazine he is looking at is mostly white, but when you see him looking around (when he hears the noise), the back of the magazine is mostly black. (Time)

Revealing: When the bats escape from the fireplace, it's obvious they are just black pieces of material.

Continuity: When the boys reach the attic Brandon fixes the flickering lightbulb. Then they show a shot of Mikey and Mouth and you see Brandon fixing the flickering lightbulb again in the background. (Time)

Continuity: If you look closely in two scenes you can see this. First the water jug in different scenes will have different amounts of water. And the same goes for the blender full of tomato juice.

Continuity: When Data is being dragged by the sticky dart in the opening sequence, the camera angle changes from in front to behind, and suddenly the distance between Data and the oil drum dramatically increases even though he is moving towards it.

Factual error: The Goonies are from Astoria, but they ride their bikes to Cannon Beach; this is where the Lighthouse Lounge is, a distance of over 30 miles. When they descend in the tunnels below the lounge, they supposedly go under Astoria Country Club and Moss Garden. This would be impossible.

Continuity: Sloth and Chunk are tied in their chairs and Sloth is trying to reach for a candy bar. First it is facing toward the camera and then in the next shot of it, it is facing away, then it switches to face away again. It could be the other way around.

Continuity: The invention the boys created with the balloon at the beginning of the movie starts off with a pink balloon. The next shot of the balloon shows the balloon is red. (Time)
