Light whisplings in Fire & Ice get 4 attacks (at +5), other types get fewer. You would probably want a water whispling, their attack is one +15 small bash or +30 small grapple. Level 1A, size small, move 80, hits 20, AT (DB) 3 (50). Does not seem excessively threatening.
The slight water elemental in RMU CrL is a little more powerful, although not tremendously so.
