Quest on supernatural creatures

Your task consists in realising a written report on a supernatural creature, giving the information we detailed for the leprechauns, brownies,... from your English school book.

That is in  fact tell about :
- where they are from
- what they look like
- what they are like
- what clothes they wear
- what they do

(of course any other information is welcome, as far as you understand what you write)
You will realise a "poster" of your creature, with a picture of it and the sentences describing it.
Only 1 English lesson will be devoted to looking for information , so you will have to be efficient when you go through the site(s)

Here are the creatures you can choose from  (unless you know of another specific one):

Dobby from Harry Potter (notice : it says Dobbie was created in reference to brownies, creatures that are described in your book!)
