I have a water baby.

The imp doesn't really like to play in his rock box when there's water in it.  He does pick up rocks and toss them into the water (the only time he's allowed to throw rocks).

The pixie doesn't really like to play outside often, so when she wants to, I try to take her outside (provided it's not too hot).  She demonstrated, today, that she will climb into the rock box when it's still got water in it from a rain storm.  Treated it like a wading pool, she did.

In her dress.  And shoes and socks.  And diaper. 

It was cute, but she was covered in mud and leaf mold.  She was still a horrible, muddy mess begging for a bath, even after I stripped her to her skin on the linoleum floor in the kitchen and wiped her down with her wet dress top.
