The Sprinkler is a craftable Structure exclusive to the Hamlet DLC. It is found in the Food Tab, requires 2 Alloy, 1 Blue Gem and 6 pieces of Ice to craft, and an Alchemy Engine to prototype. Sprinklers have a radius that requires them to be close to nearby Water. When built, a pipe appears which connects them to the water.
Sprinklers must be fueled, and the amount of fuel is indicated by a red gauge on the front similar to the Ice Flingomatic. It can accept any type of Fuel. A full tank allows the Sprinkler to run for approximately 7.5 min or 15 day segments.
If a player stands within the radius, they will quickly become wet from the Sprinkler at a rate of ~3 Wetness per second. This can be prevented by wearing water-resistant or water-proofing items (eg., Rain Coat, Eyebrella, Umbrella).
