Unlimited wishes? Cool! you think. With unlimited wishes, there's no reason not to start with your fondest wish immediately while you think about all the other great things that you might want.
"Bahiya, I wish to make my first wish," you announce formally. "I wish I was a donkey."
She nods. "As you have wished, so shall it be," adding "You might want to start taking off your clothes while you still can."
You tingle all over - was it with anticipation, or was it the change starting? Perhaps a little bit of both, you decide, as you take off your shirt. Your fingers seem stubbier and clumsier as you untie your shoes, and as you straighten back up, your ears wobble by the sides of your head as they grow in height and mass.
You fumble with your belt buckle and zipper, and shuck them to the floor. The back of your pants snag on a growing bump at the base of your spine, and as you reach behind to push them down, you feel the bump extending into a fleshy tube behind you. You cannot reach far enough to touch the end of it, and then the shifting structure of your shoulders pulls your arms forward and you can no longer reach behind yourself anyway.
Your shifting bone structure forces you to bend forward and down, and as your arms reach toward the floor, you can see that one of your fingernails is growing larger and hard as the others around it shrink back. You can feel your neck growing longer, and as you turn your head, you can see your skin start to become enveloped in a bristly pelt. In short order, you are standing comfortably on all fours, and you are engulfed in a sea of new sensations, your tail switching behind you, your ears swiveling in response to the slightest sound.
Being a donkey feels even better than you had ever imagined, you think, and you look at Bahiya with gratitude.
"Are you pleased, my master?" Bahiya asks, but in a surge of panic, you realize that you do not hear words, only sounds that no longer have meaning for you. You attempt to reply, anyway. You want to ask her "Say again?" but what comes out is the discordant bray of a jackass: "Aaaww! Eehaw! EEEEEEhaw!" Oh, this is bad, and it's just getting worse.
"You SOUND pleased," Bahiya smiles. "And what is your next wish?" You can only bray in return. Bahiya cups her hand behind her ear. "What is that? You have no more wishes, and you release Bahiya from your service? You are a most generous master!" She giggles and gives you a scritch between the eyes before beginning to turn back into mist and returning to the lamp. You have no idea what she just said, but as you see her start to disappear, you want to shout "Wait! Don't go!". But, of course, all that comes out is the bray of a jackass.
And now, a donkey stares dumbly at a dusty bottle.
