Using these L.O.L. Surprise Sidekick Swap Tots is super easy. First, take a look at your doll's initial look. To change it, simply use some water to reveal the alternate expression. Once you've seen it, carefully snap the new part into place for a fresh style. As you play, be gentle when swapping the pieces to avoid any breakage. When you're done playing, keep your dolls in a dry place to maintain their quality. If you have multiple dolls, store them together so you can continue your mix - and - match adventures later.
