Ribbit! Ribbit! Slide into summer fun with the BigMouth x Squishmallows Wendy the Frog Lawn Slide. Outlined in rows of water holes on one side for maximum slippage and a water tube that wraps around the perimeter to keep water on the slide (and away from the grass), the 18-foot lawn slide attaches to any U.S. standard garden hose for easy and quick set-up. Plus, it comes with an inflatable sled (which totally doubles as a pool float) for even more action.
