You don't know how much time you have, maybe just seconds, so you look over the row of bottles. You decide to grab one with a deep blue color.
It's tough to manipulate with your tiny arms, but you manage to lift it out of the rack and get the cork out. With a little work, you tilt the bottle over and start to drink.
It tastes rather good, almost like a wild berry. You aren't sure how much to drink, so you keep going and going until you start to feel different. You stop and look over your body hopefully.
With horror, you realize that your body is growing, but your shape is changing in the wrong way. You look at your tail and watch it suddenly length with bright feathers poking out all over the place. You squak in surprise and your tiny muzzle hardens and turns into a dark beak. The bottle falls over as your tiny arms grow into small, useless wings!
You panic a moment and flap to the floor, suddenly realizing you're in a much worse predicament. You're not only a peacock now, so you don't have the arms to open any more glass jars, but you're too big to get out of the cottage before the wizard returns!
