FInally unlocked Guppys Hair Ball
I found Cats Head in a curse room. I was carrying The Dice. Re-rolled it to become Cats Paw. Re-rolled it again later to become Dead Cat.
I believe that the guppy items draw from the curse room pool, so yes, this always happens. And no, it's not relevant to the hair ball in any way, it's an item pool thing.08:40, December 27, 2013 (UTC)
