Launch Pads are some giant yellow squares that launch you high into the sky when you jump on them. To try it out, just find a Launch Pad and hop on. Most Launch Pads are in groups so you can jump from one to another. Follow the path that these Launch Pads make to get to some really cool places. You can find them in Seaside, Snowhill, Merry Vale, and other areas in Free Realms.
You can even get mini Launch Pads for your house, they are in SC Marketplace or the Coin Shop that you can check out. They come in two sizes, large and small. The price depends on the price, or what currency you use (Station Cash or Coins).
