Kids gathered from all over to play tennis on Arthur Ashe Kids' Day in New York City!
The event included a 10 and Under Tennis area, so everyone could enjoy this awesome sport.
Arthur Ashe Kids' Day has kicked off the US Open every year since 1993! And this one looks like it was the best yet.
Fun in the Sun
The weather was fine, the rackets were up, and the tennis balls went flying all day!
Who says tennis balls have to be green? There were all sorts of fun colors on the court.
He used his Official Worldwide Day of Play Playbook to maximize his fun at the event! Way to go.
They play because nothing's better than getting fit with friends!
These guys checked out their Playbooks for more fun activities to enjoy.
Camp on the Course
Kids from Camp Woodward competed in the Street League Skateboarding 2012 Championship in New Jersey! It looks like a wild course.
Can't Wait to Skate
These guys are ready to compete in front of a live audience! They're getting fit AND famous.
Play It Out!
Your fave Nick stars played a slime-tastic live round of Figure It Out for the World Wide Day of Play!
Playing with the Stars
Getting fit is fun, especially when you're playing with Matt Bennett, Gracie Dzienny, and Lucas Cruikshank.
Hip, Hip, Hooray!
These guys are really having a ball at the kick-off of the big event!
What a Song Can Do
While the Figure It Out panel scratched their heads for clues, the lovely Rachel Crow belted out some sweet tunes!
Oh boy, it's the best slime of them all: the quadruple-slime!! These guys are great sports.
We've heard of eating snow cones, baton swirling, and stilt walking, but not at the same time! That's def one way to stay active.
Too bad there isn't any ice cream in those cones!
They're really making sure the stars get every last drop of slime. How thoughtful!
Daniella looks a lil flabbergasted! Don't worry, there's plenty more slime where that came from.
Screaming for Slime
What's that Gracie? We think she's asking for more slime!!
Peace & Leon
Leon Thomas shows his support for the WWDOP at the SmashZone tennis courts.
A day of play AND an autograph from these guys? It just doesn't get any better.
Dora and Friends
Look who showed up to play! Dora and the Turtles are super psyched for a fun day ahead.
Ready, Set, Race!
These runners have their own personal Ninja Turtle cheering squad! Now that's inspiration.
Way to go runners! This is a group of feet Raphael is actually happy to see.
Looks like Rachel put on an amazing show for these athletes!
Matt Bennett stands next to the most Foot-kicking car on the planet!
We'd give anything to cruise the streets (or sewers) in that sweet ride!
Making Your Mark
After a whole day of tennis, it's time to sign the biggest tennis ball EVER. We'd like to see them use that on the court!
SmashZone brought these awesome tennis courts to D.C. for an action-packed Day of Play.
Go for the Green
It wouldn't be a Big Help event without a green activity! These guys are having a blast painting and potting plants.
Ever wonder what it's like to be a hamster in a wheel? These guys are finding out!
Best Day Ever!
With tennis, racing, and even a visit from the Teenage Mutant Ninja Turtles, the World Wide Day of Play is definitely the best day ever.
He played tennis at the World Wide Day of Play, and has Leon Thomas's autograph to prove it!
So many people came out to run! Nothing's better than getting fit and making new friends.
Stretch n' Start
It's always important to get the stretches out before a big race like this one!
Day for Dance
There's so many ways to play, even dancing will keep you healthy and fit!
We hope the Turtles get to ride in these wheels, but let's hope they don't spill any pizza!
