Who can take on a massive wall of swinging tires? Who dares to take off down the soccer field while playing the position of...the ball?! And who has the guts to dive head first into an oo-ey goo-ey pool of globbery green slime? If you answered " the Nick Stars" to all of the above, then you're absolutely correct! Worldwide Day of Play was filled with tons of fun fit-ivities this year, but no play day game was quite as great as the ultimate Nickelodeon obstacle course!
