Colorful balls, twisting slides and cheerful animals make playtime fun with the Pop-a-Balls Pop & Surprise Ball Center. The two interactive twisting ball tracks are filled with friendly animals that will stop and start the balls or redirect the rolling. Explore cause and effect relationships by loading the balls into the ball launcher and pressing the big yellow button to send the balls up the tower, where they'll pop out of three different locations. Press the seesaw to launch the balls onto the slides. The music button introduces colors, animals and plays a variety of melodies. This tower is filled with ball popping fun!
