Peace
OOC: Actually, I believe the odds of getting a Pink Tail would be 1/65,536 or 1/65,025, because I believe there is a 1/256 (or 1/255) chance both of encountering a group of Pink Puffs and receiving a Pink Tail if you defeat such a group. At any rate, I'd bet the Genjû-summoning slot has a very small chance of getting you what you want anyway. Of course, you could always be a cheat and use save states or something.
But I never myself liked Slot very much, so I never used it much.
