Bucket of Baby Nautilus

If you are in superflat survival, you can't get a nautilus, due to the lack of ocean biomes (or any biomes at all). So, what if Wandering Traders sold a new bucketed fish type, or rather bucketed mollusk? Of course not Bucket of Nautilus, because adult nautili are too big for a bucket, but rather Bucket of Baby Nautilus! Wandy T will sell only four at a time, but that's ok, due to the ability to breed them when they grow up. But if it is just for superflat players, what's the point? So in normal worlds, to get it, you first need to breed two nautiluses. Then you need to bucket the baby nautilus that spawns. Simple as that.
