A player will have three creature weapon slots, but they're unaccessible for a player to view (A DM may be able to equip them for you if they can see your creature inventory slots)
When you make your unarmed attack for your creature weapon, it will pick one at random from the set that's equipped. If you can only equip one at a time via quickslot, then that's the one that will be used.
Change weapons with quickslotted creature weapons of your own choice, or see if a DM can attach all 3 to make it random.
