Prismapump

The Prismapump is a place-able block which you can purchase from Anita. A set of 4 blocks costs one Bronze Medal and 2 Jacob's Tickets.

USAGE
Upon placing down the Prismapump, placing down water on any adjacent lateral side or on top of it will cause water source blocks to extend in that direction. The water will extend until it hits a block or it runs off of a block. Water placed below the Prismapump will not be extended, although all other 5 sides will.

This block makes building farms much simpler, as it eliminates the need to manually place water down a line.
