For those who haven't heard, Mario Odyssey has a hide-and-seek mode call Ballon World, which too me is way to much fun.

This thread is for sharing route tips, complaining about common insanely difficult hiding spots (how are people getting 3s balloons on top of the Lost Island mountain??), and posting fun relatively unique balloon codes.

Ballon code Rules:
Rule #1: If you post a ballon code don't hide a new one in the kingdom for at least 3-days to give forum goes a chance to find it.
Rule #2: Balloons should be in-bounds.
Rule #3: Balloons should be relatively unique. Please don't post codes to anything that could be described as one of the top-3 most common hiding spots.
