Water Gnomes are found in Perry and Agents levels. A total of three appear in each level, which can be mixed with Steam Gnomes.
A player is not required to collect any Water Gnomes in order to move onto the next level, however, a certain number of Gnomes (both Water Gnomes and Steam Gnomes count toward this) are required to unlock other Mission within Perry's Story and Calling All Agents unless the player uses the "Unlockinator".
Water Gnomes require five drops of Water to be collected. All other Fluids, except Steam will kill the Gnome.
Water Gnomes have a shape much like one of a Lawn Gnome.
While full, Water Gnomes have a red hat. Their clothes and shoes appear in various shades of blue or green. Their beard is white and they have pale skin.
While empty, Water Gnomes appear in various shades of violet-blue.
