7-year-old Brock Chadwick in Biddeford, Maine was diagnosed with brain cancer back in February, he has a type called glioblastoma, and the prognosis isn't good.

To cheer him up, his great-aunt recently went to Facebook and asked people to send him cards for Halloween. She came up with the name "Brocktoberfest." And it's gotten way bigger than his family expected.

Hundreds of people from all over the world have been sending cards, candy, books, and other gifts. He's been getting about 100 packages in the mail every day. His mom says he's smiling a lot more because of it.

His family posted a video of some of the cards he's already gotten. If you want to send him something, you can address it to: Brock Chadwick, 11 McKenny Dr., Biddeford, ME 04005.
