DARIEN, Ill. -- Just outside Chicago, a young Chicago Cubs fan is battling a rare form of cancer. His family travels to Mexico for costly experimental treatments.

Muralist Ken Markiewicz, owner of Crayons Gone Wild, was so moved by Joey Ventimiglia's story, that he offered to turn the boy's bedroom into a Cubs fan's dream -- free of charge, WGN reported.

So while the family was out of town for a recent treatment, Markiewicz transformed Joey's room. He painted a W Flag on the ceiling, an ivy outfield on his bedroom wall and he even got the entire 2017 team to sign his closet doors.

And when Joey returned home, he got the surprise of his life.

A GoFundMe page was started to support Joey on his journey to recovery.

Donations are also being taken to Crayons Gone Wild so Markiewicz can paint more rooms for deserving kids.
