A friend of mine loves Adventure Time, so I made her a Finn hat and this Jake the Dog plush. It's a reasonably simple pattern, with most of the work going into hand stitching the face and limbs.
I do not own this character - I'm just a fan. :)
Cut out your pattern pieces. Take two of your big pointy oval shapes and pin them with the right sides together. Sew along one side.
Repeat with the other two pointy ovals.
Place the pairs together, and sew down the third side.
Sew down the last side, leaving a gap for turning ans stuffing.
