Don't think there is already a thread covering this... but what would you ask them?
Obviously, they would not reveal the secret just by telling us!
However, you think they can at least answer us these?
Do side missions Matter to unlocking the Super secrets?
Are there any rewards other than Koins and the infamous Ninja Star from these side missions?
Do certain Arenas, or Alternate customes affect the Final secret?
Is the Koffins WQ (or QW) a secret, or a bug?
