  • Quick
    Planning Tip

    Be smooth like a ninja and have everything go off without a hitch at your child's birthday party. The secret to party success is in the planning. Be sure to have essentials like games, food and goodie bags set up before all of your guests arrive. And it's always wise to have extras of everything. You never know when a little ninja with sticky fingers might come along and grab an extra cupcake.

  • Send The

    The ultimate invitation will magically appear at the homes of all of your child's closest friends. Sure, the USPS may offer a little assistance, but these ninja warrior invitations will certainly inspire the incognito spirit into everyone who receives one.



Wouldn't it be amazing if the moment you turned back to look at the blah party location it was already instantly transformed into a mysterious ninja den? Recruit the help of a couple little ninjas and you won't have a thing to worry about before the party starts.


Your new tricks will take you to new heights just like these fun balloons take your party's décor to new heights. Let them float above the gift table, cake table or to mark where the party entrance is.


There is nothing incognito about putting your name in big bold letters, but your little ninja is so skilled that he has nothing to worry about. Fly his name high above the party entrance to let everyone know who is the leader of the pack. When you start your secret missions, you can make the personalized banner the meeting spot for ninja headquarters or just revel in its special presence for your special day.




After all of that running, dodging, sneaking and hiding, your little ninja warriors will work up quite the appetite. Be sure to refuel them after all of their hard work and put in a special reward for a mission successfully completed. But just because the food will instantly disappear doesn't mean that you don't need to put forth the best presentation. While the food may go quickly, the tableware will stay in place, so create a stylish setting that will put a smile on those masked faces.


The fun and games are never finished. Lurking in each corner is a new surprise that will stir up the energy in the room. The moment one activity starts to turn dull, a new exciting one is already there to replace it. Work on your reflexes with games that get your blood pumping or make it a game of wits and try to figure out the puzzle before anyone else does. Ninjas are smart, quick and nimble, so be sure to work out all of your assets to keep them sharp!


Try your hand at sheer might with a ninja warrior piñata. With one swing of the ninja bat, each guest at the party will have a chance to break open the piñata to release the treasures that are hidden inside.


You may not be throwing ninja stars at your birthday bash, but you can certainly use their iconic image as decorations. These ninja blowouts will keep guests on their toes. You never know when one is blowing your way!

Wall Decals

Set the scene right with ninja wall decals. The sneakiest ninjas in your group will use the decal as a decoy and blend into the background.

Dress Up

You play the part, so why shouldn't you look the part as well? Get outfitted with the stealth ninja warrior costumes to feel like you are ready to take on any evil.



Try incorporating these fun phrases into your invitations, DIY decorations, and other pieces of the party!

"A true Ninja is a master of himself and his environment, so don't forget: We're turtles!"

"I may not look like much, but I'm an expert at pretending to be a ninja."

"Question everything generally thought to be obvious."

"A master can teach many things. But the most important lesson for a ninja is to learn oneself."

"Don't let the noise of other people's opinions drown out your own inner voice."

"True ninjas are always outnumbered, because they are individuals."

"Ninjas don't wish upon a star, they throw them."

"Asking the right questions is infinitely more important than knowing the right answers."


Party Favors

Don't let your guests leave empty-handed. After all of that hard work, they deserve an extra special treat. When they are on your side, you treat your ninjas with the respect and admiration they deserve. Make it simple by giving each guest a special party favor to help them remember this exciting day.
