Ninja Warrior Birthday Party Ideas
Planning a Ninja Party
A ninja party runs $100-200 for 10-12 guests. Five trials: silent crawl (under a string web), throwing-star toss (paper plates at a target), balance-beam (2x4 on bricks), break-the-board (foam squares), final stealth-strike. Each trial = one belt color.
The real talk on a ninja party
βNinja parties are obstacle courses with sashes. Black t-shirts + dollar-store sashes + 5 stealth/balance challenges = a complete party in 90 minutes.β
What it really costs
$100-200 for 10-12 guests. $18 sash 12-pack + $20 of pool noodles for ninja-warrior obstacles + foam break-boards = the course.
The constraint that matters
Five trials: silent crawl (under a string web), throwing-star toss (paper plates at a target), balance-beam (2x4 on bricks), break-the-board (foam squares), final stealth-strike. Each trial = one belt color.
Don't do this
Don't buy real foam swords. They become weapons in 4 minutes. Pool-noodle staffs wrapped in black tape are softer, cheaper, and survive longer.
No signup. No credit card.
