Head over to the Roblox website and create an account for yourself. Then all you need to do is click on the 'Avatar' tab on the left side of the screen, where you’ll see your avatar ready to go.

Go to your Avatar and bring up the Avatar Editor. Here, you can now select one of the slots on the ‘Equip Emotes’ wheel and add any custom emote or dance you’ve purchased from the Roblox Store.
