Drug him. It's what I'd do.

Take away his phone and hold it hostage

Hold him at gunpoint while you tell him to go to sleep.

Well, I would like not to hurt or harm him with a drug. I have tried to hold him at gunpoint but I only have a slingshot and there is only a model gun in the room. And maybe holding his phone hostage would be a good idea.

Tell him he's tired and should go to bed while not letting him leave his house or do anything.

Get a real gun then.

Tie him up.

I cant get a real gun the way i am, also got no rope. I also already tell him hes tired, and lets not do that today.

pretend to be a scary monster and scare him to sleep

Get help from a friend or friends.

My friends all influence him on going out....And Im not scary enough.

If you have some kinda thieving group maybe you would be able to get some of them together and peer pressure him into sleeping. That would work well.

Wait til he goes to the Metaverse then he will be to tired to do anything but go to bed

Annoy him for so long he stays awake and let him pass out from being tired.

Simple, just pause time and tuck him into bed.

Ill just scratch the hell out of his face.

Install a door, and lock him in his room.
