I made a little house elf for my partner imera in the one tiny thing swap:

It was inspired by Angry Angel's
Dobby Doll. I really wanted one, but I wanted a smaller one, to fit Harry Potter themed amigurumi that I usually make.
Size reference: Lucius in this picture is about 5 inches tall.

Some technical information:
I used cotton yarn, fibre fill and a 2mm hook, the eyes were 5mm. Unfortunately, I couldn't get green eyes that small (Dobby is said to have green eyes in the books), so I used brown ones.
The clothing is just a bit of paper towel. I only wanted to use it as a template for a cloth piece, but it had the ragged look and fit well so I left it on.
Edit: I feel so cruel not to have given him clothing... but he was supposed to be with Lucius. But if you make a Dobby, perhaps you could give him a sock?
House Elf Amigurumi Pattern:
For private use.
This pattern is easy, but requires you to know how to make increases and decreases when working in rounds.
Head:1) ch 2, 4 sc in 2nd ch from hook (or 4sc in a magic ring)
2) 4 sc
3) 6 sc
4) 6 sc
5) 12 sc
6) 18 sc
7-11) 18 sc, insert safety eyes
11 to end) decrease each round by 6 sc, stuff head firmly, close.
The face gets a sorrowful shape if you use safety eyes that allow you to thread some cotton through and pull it very tightly to the back of the skull so the eyes sink into the face a bit. If you use safety eyes that have washers to keep them in place, you can do the shaping by pulling back the eye sockets with a thread. The back of the head will flatten a bit if you do this, but it's not too bad.
Edit: In the meantime, I pull the thread that sinks the eyes in through the throat area, so no more flattening of head.
Ears: (make two, work in rows, not rounds):
1) ch 2, 2 sc
2) 4 sc
3) 6 sc
4) 8 sc
leave a long tail for sewing the ears on later
Legs and Body:1) ch 2, 6 sc in 2nd sc from hook (or 6 sc in a magic ring)
2-6) rounds of 6sc, cut thread, leave long tail
7) make another leg the same way, but don't cut off yarn on the second one. continue with a round of 12 sc over both legs. Neaten crotch by sewing shut with leftover tail from first leg
8-13) 12 sc
14) decrease to 6 sc, cut off yarn, leave long tail.
Stuff body
Arms:1) ch4, 4sc in 2nd ch or 4sc in magic ring
2-6) rounds of 4 sc
leave long tail
Finish:Sew on ears in a curve.
Pin all parts in place, check posture (for example, if you want the slightly sidewise turned head), sew on head and arms.
Dress in rags.
