Mailbox (object)

The mailbox is a mysterious, sentient, and omniscient object that Dipper Pines and Soos found in the woods.

History
Dipper and Soos found the mysterious mailbox in the middle of the forest. It was without a house or address, so the two decide to test what would happen if they try and mail a letter, expecting someone to pick it up. Instead, the mailbox rumbles and raises it's flag, indicating it has a reply. After several back and forths, Dipper decides to ask it who wrote 3|journal #3, but before he gets the chance, Mabel inserts a video of herself inserting 100 gummy worms up her nose, to mail to her mother. The mailbox finds the video insulting, and disappears in an implosion.

Trivia

 * While the rest of its letters were without, the first letter it replied with had a wax seal with an infinity symbol on it.
