Two Moms Plan
A Birthday Party...

One stresses for weeks. The other just shows up with a cake.

The Stressed-Out Plan

  • Spends three weeks planning a Pinterest theme
  • Drives all over town for decorations and favors
  • Sets up the morning of, and stresses about it
  • Manages twenty kids alone while they take apart the house
  • Cleans pizza out of the carpet at 9pm
  • Hopes the kids actually had fun

The Zero-Hassle Plan

  • Books one date with one phone call
  • Shows up with just a cake
  • Watches our instructors run every minute
  • Takes pictures while twenty kids burn off their energy
  • Walks out. We handle every paper plate
  • Watches her kid break a board and cut the cake with a sword

Be the second mom. Your weekend will thank you.

03 / The Signature Moment

The Moment Every Parent
Pulls Out Their Phone.

Every birthday party has cake. Very few have a samurai sword. Friends gather around, our instructor guides the birthday child's hands, and the whole room counts down. It is the photo that ends up on the refrigerator and the story they tell at school on Monday.

04 / The Highlight Reel

Three Moments That Make It Unforgettable.

These are the moments kids talk about at school on Monday. They are the reason guests beg to come back.

Moment 1

Board Breaking

Every guest breaks a real board. The look of shock, then pride, then pure joy? That is the moment parents wait for, and the whole room erupts.

Moment 2

Samurai Sword Cake Cutting
