Currently, the only version of Minecraft that supports any of these is the Java Edition. Bedrock players can't get custom heads yet, unfortunately. Here's how to get them on Java Edition.

Originally released in Minecraft: Bedrock Edition 1.16.100.52 beta, the /ride command is finally coming to Java Edition in update 1.19.4.

You can get a command block in your Minecraft Java or Bedrock world using cheats and a special chat command.
