Remember the power-up you could get in Super Mario Galaxy? That's right! With this datapack, anyone wearing the Cloud Hat can place (up to 3 at a time) clouds to stand on. They will also receive a small jump boost effect because otherwise, the ability is useless.
NOTE: To receive the ability, you must wear the Cloud Hat. To get it with the right NBT, type /function give_cloud_powerup into the chat.
