Trivia

 * It is the third treasure which can be obtained as an event reward.
 * It is the first event-reward treasure that has Power+.
 * It is also the first treasure ever which has the expiration date (the effect is not permanent).
 * After the expiration date, this treasure will not be deleted. This is done so users can use it in their preferred way of extracting for Magic Powder, selling, or keeping it as memory of the treasure after the expiration date.
 * Contrary to other treasures with non-permanent effect, the Hat's effect continues to appear beyond the expiration date (as of January 2016), making it de facto permanent Power+.
