My kids get so muddy/dirty too when they play in water. You asked a while ago about the water slide I had on my blog. It is the brand that is at Target. My parents bought it at Aldi. I was surprised at how sturdy the fabric seems. We have used it for a while now and the boys love it. It is expensive, but if there is a willing grandparent or aunt or uncle, you cannnot go wrong. The kids will love it.
