A group in Charlottetown is challenging people to build 'the biggest, the baddest, the boldest, the most ridiculous cardboard box fort' possible in support of the Children's Wish Foundation.

Amanda Rae Gallant is organizing the fundraiser. She got the idea from a birthday party she and a friend threw last year. Her friend's house was transformed into an enormous blanket fort.

"We had such a great time acting like a bunch of big kids that we thought, 'What about cardboard box forts?'" Gallant told CBC News.

Gallant has organized three charity fundraisers in the past. The theme appears to be getting bigger and more foolish every year.

Teams of up to eight people are being invited to join in the fundraiser. Some boxes will be supplied, but teams are welcome to bring more.

"Each of those groups are going to be building the cardboard box fort of their dreams," said Gallant.

"It's going to be a literal cardboard box war. You'll be challenged to build the biggest, the baddest, the boldest, the most ridiculous cardboard box fort you can."

Gallant said the Children's Wish Foundation seemed like the obvious beneficiary of the fundraising event.

The fort-building challenge is scheduled for May 14 at the Murphy Centre in Charlottetown.
