A 3-year-old boy with a terminal disease had a simple wish — to see snow. His mother, with some help from friends and volunteers, made it happen in spectacular fashion.

Mason Williams was born with hypoplastic left-heart syndrome, the Daily Mail reports. He requires an operation but is not yet well enough to undergo it. He is also unable to speak due to a chromosomal disorder, according to the report.

Seeking to grant one of Mason's wishes, mom Melodie, who lives with her son in the parish of Rowley Rigis in England, set out to transform her front garden into a snowy dreamland. One problem: There was no snow. With the help of local businesses, Melodie fixed that by bringing in 105 gallons of snow to surprise her son.

Melodie told the Daily Mail, "I just had to do something now in case he's not alive next time it snows. If I didn't do it now, and something happens to him, I'd never forgive myself for not making the most of the time we had."

From the looks on Mason's face, he was very pleased with his mom's handiwork.

Yahoo News U.K. spoke with Melodie about the generosity of the companies and individuals who helped her realize Mason's dream.

Melodie told Yahoo News U.K.: "I am so grateful to everyone who helped us. Things like this just don't happen to me. I'm so lucky that I could make this happen for Mason."

The 3-year-old spent about an hour playing in the snow and was reportedly delighted by the surprise. Said his mother, "He laughed and giggled as he touched the snow. He can't speak, but I knew he was loving his treat. Watching him was amazing; I will remember it forever."
