Pbs Kids World was an educational software made by PBS Kids back in 2009(?) Little is known about the software, but it included games and videos you will play, and then you will win a prize that you can print out. Images and videos of the software are very rare, including the commercial that aired on the channel. There are currently no evidence of the game right now.
(UPDATE) PLEASE DELETE THIS ARTICLE! THE GAME WAS CALLED PBS KIDS ISLAND! GO SEARCH THAT INSTEAD! MY BAD!
