In Minecraft, all entities and the player's characters have a specific movement speed and size. Some mobs are massive in size, while others are incredibly tiny.

Minecraft Java Edition is one of the few games that allows players to install any kind of mod and use it in the game.

The only official ways to get a cape in Minecraft are by attending special events or buying skin packs, but Java Edition players can also use mods.
