Your kids can become human bowling balls with the Banzai Slip ‘N Six Pins. It’s a 16 foot long water slide with a 3 foot long inflatable tunnel. After you slide through the tunnel you come upon the water-filled splash bumper pool and the 6 silly inflatable bowling pins:

Slide over and over again until you knock them all down, or cannonball down the slip ‘n slide and go for a splashing strike. The bowling adds a fun dimension to a standard water slide and it’s pretty reasonably priced (and got pretty good reviews too!). The repeat play factor on this is definitely higher than a regular slip ‘n slide (you definitely don’t want to set up a water slide in your backyard only to have your kids come back inside within 10 minutes with “I’m bored”). This one looks like a winner.
