Also, against all odds, Butler is actually imagining exactly what Kris meant to say.
"Well you gotta get water first, then you find a nice steep hill and sorta dig it out to make a slide shape. Then, when you pour the water down, you get a nice slippery slide made of mud!"
Kris is sorta treading water, since she's juuuust short enough so her feet don't touch the surface.
