A B.C. father has pulled out all the stops this year so that his young son will feel included in Halloween festivities, despite his health-related mobility challenges.

Four-year-old Jackson Pool, of Sidney, B.C., is a big fan of Scooby-Doo. This Halloween, he’s very excited to dress up as his favourite canine character.

But thanks to his dad, Chad Pool, he’ll have a great costume accessory.

Chad turned a child-sized wagon into a miniature “Mystery Machine van” so that Jackson, who has mobility challenges linked to cerebral palsy, isn’t left behind during trick-or-treating time.

It took a lot of “late nights” to get the wagon looking just right, Chad said, adding his son was thrilled with the final product.

“The surprise on his face when he saw it, bouncing around and laughing, it made every hour I put into it worth it,” Chad told CTV Vancouver.

The whole family is getting in on the act. Jackson’s mother is dressing up as Velma while dad is going as Shaggy.

This isn’t the first year Chad has put extra special care into ensuring his son has an inclusive Halloween.

Last year, Jackson went as widower Carl from the animated move “Up.” His ride? A wagon designed to look like the film’s balloon-topped airborne house.

The Pools aren’t alone in dreaming up news ways to make children facing difficulties participate in the joys of Halloween.

Magic Wheelchair, a new U.S. charity, has volunteers teaming up to make epic Halloween costumes for children in wheelchairs.

The organization has turned kids’ wheelchairs into dragons, elephants and boats, to name a few.

“Those are the things that define us when we have challenges and trials and hard times,” said Ryan Weimer, who co-founded Magic Wheelchair with his wife.

Pool says it’s likely his own creations for Jackson will get more elaborate each year.

“I often joke: At what point do we stop calling it a Halloween costume and start calling it a float?’,” Pool said.

Now imagine how happy Jackson will be when his sweet ride is full of candy.
