Hey, it's you! Yea, you! The one who helped me last week! Mind helping me out again?

So, as I feared, we're still missing a lot of letters, and I mean A LOT. Anyways... could you please lend me a hand, again?

I knew your name was on the Nice List for a reason! Thank you so much! Here, take this sack: it's the bag that Santa uses to collect people's letters, okay? All you gotta do is open it next to anyone who may have a letter for Santa, collect some letters, and bring them back to me! Get me... 10 letters from the El Nath Mts. and Aqua Road. Thank you!

Huh? B-but its the holidays... That's worthy of the Naughty List for sure...
