I’ve been wondering this for a while but haven’t been able to figure it out. On the Xbox (or Microsoft) version of Minecraft, are you able to use the features from a preset world in the market place within a custom world?

For instance, a world that has unique mobs added in, am I able to take those mobs and use them in a custom world of my liking? Or are they restricted to just the preset world you bought? https://routerlogin.uno/
