I decided to make myself an otter boi after seeing all the cute art of them. He has 2 forms, all the grey looking string coming out of him are candle wicks and he can light them up whenever he needs, which also lights up his eyes. I really wanted a spooky boi, and something simple but unique, and I am pretty satisfied with the result.
BOO IS NOT FOR SALE AND I DID NOT DRAW THE LINES FOR THIS. This otter was made with a base that can be found here. The base has many different combinations you can choose from to make your character as unique as possible, without breaking your bank ^-^

NOTE: THE BASE DOES NOT COME WITH A BACK SIDE, ONLY THE FRONT. I had to edit the front to get a back for this ref sheet, please keep that in mind if you choose to purchase. Its still a wonderful base and I recommend it for anyone wanting to make an Otter themselves.
