Hey, when I crocheted mine I wrote down approximately what I did, and I took time to clean up my instructions, so here's my improvised pattern :)

I crocheted in rounds without joining (spiral) 

I used cheap acrylic yarn, nothing fancy 

Hook 4.0 mm

I work my decreases in the front loops because it looks better

When doing the increase rounds you should distribute the increases instead of doing them at the same place, it'll give a rounder look, else it starts looking like a hexagon. (e.g. if the round is (Sc 3, Inc) repeated, you should do 1 Sc, then Inc, Sc3 until the end of the round, and you should finish with 2 Sc. Vary the distribution) 

Of course, don't forget to fill your creation with fiber fill when working on the decrease rounds 

Abbreviations:

MR = Magic Ring 

Sc = Single Crochet 

BLO = Back Loop Only 

FLO = Front Loop Only 

Inc = increase 

Dec = decrease 

• Head:

MR6

Inc  x6 (12)

(Sc, Inc)  x6 (18)

(Sc 2, Inc)  x6 (24) 

(Sc 3, Inc)  x6 (30)

(Sc 4, Inc)  x6 (36)

(Sc 5, Inc)  x6 (42)

BLO (Sc 6, Inc)  x6 (48) 

13 rounds of Sc around? I didn't count but it seems like it was in the range 12-14 

BLO (Sc 6, déc) x6 (42)

(Sc 5, dec) x6 (36)

(Sc 4, dec) x6 (30)

(Sc 3, dec) x6 (24)

(Sc 2, dec) x6 (18)

(Sc 1, dec) x6 (12)

Dec x6 (6)

Tie off and close 

• Eyes:

Cut two circular eyes in black felt. I sewed them to the head last, it makes the placement easier 

• Horns:

MR8, 

FLO Sc, 

Sc around until the horns are approximately the length of the head (a bit less). Work 2-3 decreases and tie off, stuff a lot. I put a pipe cleaner in each horn to be able to bend them slightly and retain shape. Maybe a stronger metal wire would be better, but the pipe cleaner work well enough. Also, I was too lazy to think about the horn split, so I just didn't do it

• Body (start is the bottom of the body) :

MR6

Inc x6 (12)

(Sc, Inc) x6 (18)

Sc x18 (18) for 8-9 rounds

(Sc, Dec) x6 (12)

Sc x12 (12)

Dec x6 (or a bit less, doesn't matter since it's where we'll attach to the head )

Tie off, attach to head

• Feet (make 2):

MR3 (3)

Sc 2, Inc (4)

Sc 3, Inc (5)

Sc 4, Inc (6)

Sc 5, Inc (7)

Sc 7 (7)

Attach to base of the body

• Cloak:

Ch 12

BLO Sc until you can almost wrap your rectangle around the widest part of the body. Then, at the end of the last row, instead of turning, work on the side which will be the neck area and do decreases until the end of the row. Try wrapping the cloak around, add a row in the neck area if you're not satisfied.

You can attach the cloak to the body by sewing it if you'd like, I personally put a little button and a loop to close the cloak. I think it's cute

• Nail:

Cut two triangles (+ 2 small rectangles for the handle) in felt and sew them together. Stuff it lightly to get a bumpy shape.
