Roller Coaster for kids toy review of the Step 2 Extreme Rollercoaster. DisneyCarToys roller coaster compilation where the kids play fun summer games like water balloon fights, Mr Bubble Foam Soap and other family challenges on the fun plastic Step 2 rollercoaster. This roller coaster is the biggest backyard rollercoaster sold by Step 2. It has lots of bumps and goes pretty fast. We also put foam soap on the ride to make it more slippery.
