Greetings, 'Shroom readers! This is Lord Bowser here with a special announcement for you all; Lakituthequick (talk) and I have put together a scavenger hunt, with a twist, for this issue of The 'Shroom!
Twelve Power Moons have been hidden across the entire issue, and it's up to you to find them, but here's the catch; they're all invisible! You will need to find Hint Art, found within our written sections, in order to ascertain the location of the invisible Power Moons. There are twelve Hint Arts total, and they will be hidden in oddly-formatted text within our sections, so be on the lookout for anything weird out there!
In order to participate in the scavenger hunt, please fill out LTQ's provided sign-up form right here. This will activate the Hint Arts and their respective Power Moons for you to find. You'll need to find the Hint Art first before being able to collect its Power Moon. There will be rewards for the first few players who find all twelve Power Moons, so get to it if you'd like to have them!!!
If you have any questions regarding the scavenger hunt, please direct your concerns to either myself or Lakituthequick (talk). We hope you enjoy the hunt, the holiday special issue, and your own holiday festivities!
