Herbs should only spawn on certain tiles
Currently, we've got herbs spawning on the docks.
We could do something like this:
Moonbell: {
sheetName: 'tiles',
cell: 50,
itemSprite: [1, 1],
spawnOn: [0, 2, 6]
}
Ideally, the tiles referenced should be the original tiles of the map, not the random variations they map to.
