Agreed, this is an amazing fight of epic proportions and really tiny arms. We definitely want players to have more chances to experience it. The epicness should be about fighting it, not about finding when it spawns, even though that can also be somewhat fun as long as the timer is not so long that it gets frustrating.
You should be able to find Mr. “Tiny Hands” 乌达斯塔
a bit more often now.
