It's games galore as Barney, Baby Bop, BJ and their friends Jason, Jesse, Kristen and Min try to activate Barney's spectacular Game Machine. Apparently it's empty, and needs to be filled with lots of playthings before it will work. The group collects toys from games they've played and adds them to the Game Machine until a shudder, a quake, and the Game Machine explodes into action! The most fantastic game board appears and allows the children and dinos to participate in the best game day ever!
