* Special fishing tiles will move with the seasons and provide different fish. This occurs at the beginning of a [[Wurm Universe|season change]].
* Non-special fish types may be caught on special tiles, but special fish can only be caught on special tiles, and a lesser chance if close to a center spot.
* These areas can overlap, so its possible to find places where two special fish can be caught.
* Aside from blind searching and perhaps some luck, a [[Lurker in the deep]] pendulum can be used to locate these special tiles.
* Special fishing tiles can disappear if the terrain around them is modified.
