2 in 1 first one the one you have to breed can evolve First get marril and the sea incense (the sea incense is in 5 island cave (on pokemon leafgreen/firered)The sea incense is in the boat in the water in between dewford and the other town that you can buy soda pops from (on ruby/sapphire) you have done that part) Then breed marril with (another marril or a ditto) (marril needs to hold sea incence) you will get azuril and if marril is not holding sea incense marril will hatch from egg
