"But we just demonstrated that it's reversible!"

"Not necessarily! Maybe it just happens that this rock is 'male', this is 'female', and each of those are like 'blue skin', 'bad hearing' and 'has no legs'!"

"It could be that one is 'reset' and the other is 'female'."

"It could! But it also might not be. In which case I might be stuck with whatever it does to me."

"That's a risk I'm willing to take."

…

Well okay then. He goes and taps another rock.

Now he has blue hair!

Like. Cyan blue. Imagine a cyan highlighter. That color hair.

He notices it! He can see a bit of his hair!

"… Well that wasn't too bad."

She wasn't expecting that argument to work. Cool.

"Now try the first one again."

So he does! … It does not in fact change his hair color back.

"Um."

"There's that hypothesis disproven, then."

… He taps the second rock.

Now he's female and he no longer has the highlighter cyan hair!

So he or she taps the first rock again.

Male again! … Does not in fact have the highlighter cyan hair.

"Okay, well."

"Oh, that's useful! Now we can try them all!"

"By 'we', she means 'you', in case that wasn't clear."

"Orrrrr we could both try them."

The animal seems less distressed but now seems like it wants to sigh.

Ugh.

"I'm not actually curious enough to try one myself."

So he sighs and goes and taps, like, five.

One messes with his eyes – they look more like human eyes, except it's an amber iris. One messes with his height – he in fact gets like half a foot taller. One makes his ears slightly pointier and also reduces how well he can hear. One makes his hands gain a finger, each. One decides that his spine is wrong being all straight and it should try being crooked instead – the process is slightly painful but not debilitating and he manages to undo it with the female and male rock things.

"I'm not sure I want to test the others," he says, looking at the three that are left over.

One has decided to glow ominously red.

He's so suggestible, this is wonderful.

"At least do that red one."

He taps the female rock, then she gives Elleira a flat look. "It's red. It's literally ominously red."

"Right, which means it's different from the others. Don't you want to find out how?"

"Not… not really?"

"We've come so far, though. Why stop now?"
