You can create your own love path tile by flattening a low area close to open water and planting flowers on all of the tiles. The rules for a tile to become a special tile are:
* There must be water closer than 20 tiles away. It's easier to create a love tile if you aim for it to be 5 or more tiles from water.
* There must be at least 4 tiles with flowers within a radius of 2 tiles around the special tile (forming a 5 x 5 area).
* The special tile must not be 10 dirts steeper than surrounding tiles.
