When I was little, a dinky but enormously charming Snoopy sprinkler ruled my summer (that and my Snoopy sno-cone maker). This sprinkler is a definite upgrade. It, as its name suggests, wiggles. It spits and spurts and spritzes all over, unpredictably, as the best sprinklers do. And as it does your little one and her friends will boogie along and shriek with joy.
