Allay duping with clusters

All right, Im seeing a bunch of ideas to make allay duping more challenging. Obviously the current method is too simple, but I get all the ideas you wanted to implement. 1. Renewable item should be used. 2. Music related, cheerful vibe. 3. Not too easy to make. If an amethyst cluster is used in the process of allay breeding, this makes the allay just slightly more challenging to breed. My idea started with the allay being born from the amethyst cluster, as if it were their egg of some sort. Let me explain the full process. 1. An allay is dancing to the music. 2. When given an amethyst shard, it enters love mode and searches for an amethyst cluster. 3. When it locates a cluster, the allay sprinkels fairy dust on it, the amethyst shatters, and an allay comes out from inside. This is the general idea I have got, of course minor changes can be made to balance things out or give an asethetic to it. Option 1: the amethyst cluster must not be fully grown when it is being 'fertilized'. In this case the allay will emerge from the bud when it grows into a mature cluster. ---> I actually like this one more now that I have this idea. The fertilized bud can have a bluish glow to it, which will look cool, while limiting the player from hoarding a bunch of silk touched amethyst cluster to easily reproduce the allay from home.
