Continuity mistake: After Andy kisses Mikey, when she tells Stef about it, her long hair is at her back, but in the close-ups her hair is in front of both shoulders, but next wideshot it's all behind again. (01:14:10)
Continuity mistake: In the attic scene, right when Mikey scolds Mouth for ruining the painting, you can see Brand standing next to the plasma lamp which is turned off. In the next shot of Brand reading the book, the plasma lamp is on. (00:14:50)
Continuity mistake: When Stef explains to the others why they shouldn't take the coins of the well, Mouth is standing next to Data silently counting the money in his hands. In the next shot of Mouth explaining how his wish didn't come true, he is now standing farther away from Data. (01:01:20)
Continuity mistake: 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. (01:27:25)
Continuity mistake: 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. (00:12:25)
Continuity mistake: At the country club, when Troy is going into the bathroom stall we can see the back and front cover of the 'Guns & Ammo' magazine he is looking at, but when he hears the noise and looks around he is holding a different issue of the 'Guns & Ammo' magazine. (00:51:00)
Continuity mistake: When Brand takes Data's sister's bike, there is a horn affixed to the handlebar which disappears when Troy pulls up beside Brand in his car and then reappears when Troy starts speeding holding Brand's arm.
Continuity mistake: We see Mouth climb down into the fireplace passage after Brand and Andy. We then see a close-up of Stef's pink high-tops descend, being helped by Mouth (we see his rain slicker), who's already down there with Brand and Andy, who are visible in the background. It cuts to a close-up of Stef, with Data's white Nike high-tops climbing down after her. But the next close-up is of Mouth's feet (black Nikes) just coming down as Brand grabs his ankle and says, "Come on!" Impossible since Mouth was already down there. (00:45:20)
Continuity mistake: When the boys reach the attic Brand fixes the flickering lightbulb. Then they show a shot of Mikey and Mouth and you see Brand fixing the flickering lightbulb again in the background. (00:14:04)
Continuity mistake: When the Fratellis are trying to get information from Chunk, the amount of juice in the blender changes between shots.
Continuity mistake: On the beach, when Mr. and Mrs. Walsh leave the van and then rush to Mikey and Brand, Mikey's knit hat is pulled down low over his ears, but next shot it is folded up above his ears, though he never touches it. (01:41:55)
Continuity mistake: When Mouth first shows up at the Walsh's, in the wideshot as Brand is stretching the chest expander, Brand's left leg is crossed over his right, but in the close-up it's right over left. (00:06:30)
Continuity mistake: On the beach, when Mikey tells his father, "We had our hand on the future, but we blew itÂ…," in the close-up the brown blanket is only on Mikey's left shoulder, but in the previous and following shots the blanket is snugly around both shoulders. (01:45:25)
Continuity mistake: Chunk is tied to a chair when Jake and Francis leave him in the room with Sloth. When Chunk introduces himself to Sloth, the rope around Chunk's right shoulder has gone up, off the chair, but then manages to lower itself again, back over the chair in following shots. (01:04:05)
Continuity mistake: At the end, when the Fratellis show up on the beach, Chunk and the others run over to Sloth to protect him and Chunk stands on a large boulder. The ground is rocky and the sand is brownish. When Chunk tells Sloth that he'll live with him, in the overhead close-up Chunk is now shorter than Sloth and the ground is pristine off-white sand. (01:44:10)
Continuity mistake: 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.
Continuity mistake: When Sloth is trying to reach for the Baby Ruth, the candy bar's position and the way it faces changes between shots.
Continuity mistake: When the Goonies are standing behind the waterfall in the cave underneath the wishing well, they've got dry hair. But just before Mikey walks through the waterfall, you can see that his hair is soaking wet already.
Continuity mistake: When Sloth kisses Chunk for sharing his chocolate, Chunk's cheek swaps from dirty to clean between shots.
Continuity mistake: Before Chunk opens the Fratellis's door, Data looks at Mouth, and then turns his head at Chunk while smiling. A frame later, from a new angle, he is still looking at Chunk and repeating the previous movements.
Answer: He says, "He is a big strong man."
