This was a Halloween that Chase Fuller will never forget.

7-year-old Chase was in a serious car accident with his dad and brothers back in April. He suffered severe spinal cord injuries and has been recovering at Mary Free Bed Rehabilitation Hospital in Grand Rapids ever since.

Obviously, the staff at Mary Free Bed works extra hard to make holidays special for the kids staying there, and Chase is no different. They helped him make a Halloween costume of his favorite celebrity DJ, Marshmello, including a DJ booth around his wheelchair.

His family posted an update to their Facebook page and, within days, Marshmello had shared the post on his own page.

The caption said, "Moments like this make me so happy. Keep smiling, Chase."
