Hi! If you play Java edition you might have this problem: "why do other editions have arms on their armour stands and we don't?!" I know people have made clever build hacks, but those aren't needed! there is a command for the arms! It is:

/data modify entity TypeInName ShowArms set value 1


TypeInName, Please do not type this in, to do this command have your cross pointing at the armour stand. When it goes to the part where you should type in the name click the bit that has numbers and letters, which honestly look random!


Hope this Helped!
