The Sacred Crown (神聖な王冠) is a special crown that is kept on the top of Mount Rumble.
Overview
Once someone puts the crown on, it attracts thunder and is shown to be stuck to the user's head until they get shocked by the lightning.
Goku was given the task of retrieving this crown as part of his training under Mr. Popo. Although Goku failed to retrieve it several times, being hit by thunder in all of his attempts, his agility and sensing improved.[1]
