can you use at peka glade?

you can also use bottles other than the Pitcher, HOWEVER I wouldn't recommend even looking at them, since they turn your pet into an ugly camel-thing once you feed the water to them. :C

ooh. So the pitcher is what gives you the glade potion?

You need that pitcher to turn your pet into a glade pet!

But you can sell your filled bottles for a good price if you'd like to make money.
