Touch horn

I decided to present the idea with a new horn "touch horn", it will be created like this, for this we will need a new item "Warden sensor" and the goat horn itself. How do I get an item from a warden? It needs to be killed, but the probability of this item falling out is very small - 3%. What will the horn do? It will make a very loud sound, and therefore the varden will run away from it, but the horn has only 3 uses. I hope the idea will be approved :) P.S: I did not come up with a texture for the horn, but there is a texture of the warden's ear
