I think water burst is closer to the spirit of the original (kill her foes with water).
I also found this:
Water Jet (Sp): As a standard action, a water grue can create a tremendously powerful 30-foot line of water. Any creature in the area of the line takes 2d6 points of damage (Reflex DC 11 negates). A creature failing the saving throw must succeed on a Strength check or a Balance check (DC 5 + damage dealt) or be knocked prone by the force of the blast. This is the equivalent of a 2nd-level spell.
