Sloth's dislike for his brother's singing may seem like a case of the former being a "tough crowd," despite the latter's singing being more than decent. But then one learns of Mama Fratelli's influence on his physical and mental state, and it all makes sense. Sloth isn't bothered by his brother's singing because it's terrible; he's annoyed because it sets him off.
Probably an obvious one but the four main Goonies, Michael (Mikey), Clark (Mouth), Richard (Data), and Lawrence (Chunk), are all primarily known by their nicknames. Honorary Goonies are Brandon (Brand), Andrea (Andy), and Stephanie (Stef). Also, note that Sloth's real name is Lotney.
Mama Fratelli's interrogation methods with the blender. Even more chilling when you realize this was just for starters if Chunk didn't talk. (Though it's essential to keep in mind, she may have been bluffing.)
Chester Copperpot's demise. His legs get crushed, he's pinned under a boulder and doubtlessly in tremendous agony. And there's nobody to help him. Since the legs don't contain vital organs, he probably lingered like this until he died of shock or thirst... and that could have taken days on end.
They do include some very powerful arteries, though. He could have bled to death in minutes if they were severed. Not pleasant, but certainly not as bad as dying of thirst.
Slapstick or not, Troy's cruel prank on Brand could be construed (and charged) as attempted murder.
"Break...FALL...!" can easily be this. It's almost as if the film's implying that Sloth's physical and mental deformities resulted from being dropped as a baby. What a disturbing thing in a kid's movie!
Ma Fratelli confirms it as she admits to dropping Sloth once when he was a baby. Or twice.
