Idea for good MC challenge and punishment?

Wants to do a new Minecraft Challenge with my friend this time with punishment do you have any ideas? (Nothing perverse please!)

Money.

Should it just be a punishment in the game or also in real life

A speed run

A punishment can be both, it doesn't matter.

Who first defeated the dragon?

Super secret settings (e.g. Reverse screen) and thus win a round of something, the loser has to get the other premium.

Survival:

Who will be the first to kill the Ender dragon?

Loser has to eat something gross or something

As a punishment the winner may. Select the other's skin. He then has to keep it for 1 week. Then as a challenge. Who gets damage first or something.

MEGA GOOD IDEA!

Then the loser has to fight against 2 wither

Must throw his best items in lava

Must do 100 pushups

must eat until it bursts

I can't think of anything more spontaneously

I'm glad you like it.

So without anything against the wither? Good idea!

Thank you

Yes.

Preferably in one world
