What's that? Do you want to become an upside-down chicken? Sure!
This perk allows you access to 1 custom disguise of your choice. It can be any mob in Minecraft, including blocks, players/skins, some particle effects, etc. If the mob has special effects, like a baby form, that is included (ie. a Turtle disguise comes with adult and baby).
While disguises are available on all servers, keep in mind disguises are blown when attacking or being attacked and are not allowed in tournaments!
While player skins are allowed as disguises, anything intended to impersonate staff or celebrities is not allowed.
