go to the black cat called ebonysong talk with him and he says to ome back tomorrow do that the he should have a rock for you

You go ahead to Fallenclan's territory and ask Ebony ( Idk suffix). You'll have to wait a day or two days or maybe three, then check out the territory. You'll see there's a rock. You click on the rock and walk to your territory and click on Robin to place it or just go back to the place where you decided to bury.
