The solution is simple

BRO I ALREADY TAPED THEIR MOUTHS SHUT, AND THEY’RE STILL SCREAMING LOUD AF

Would you like to borrow my pipe grenade

Ok here
*gives*

Amateurs, sow their mouths shut

Amateur, rip out their vocal cords

Amateur cut their head off

Amateurs, feed their souls to the beast.

Amateur chop them in little tiny pieces and lock them in a chest

Amateurs, eat their mouth

Amateurs fill their mouths with hot glue

Amateurs, choke them out.

Amateurs, just pry their mouths open until they scream so loud they burst their vocal cords.

Amateurs, rip their spines out so they can’t live so no noise no life free food

Amateurs
Run them over with a army of crusaders

Amateurs, chop up their limbs and spine so they
1) die of loss of blood or
2) shut up from the pain and crying so much

Amateurs, bombard them with anime stuff till they die from digust.

Amateurs, tie them on a plane so when the plane hits the ground the kid’s head falls off

Or dispose them

Eat their vocal cords

Shi

You could just kill them, you could still use them for whatever reason you kidnapped them for in the first place

No just remove the vocal cords. Much more effective, but it’s a hard process
