This is a Pokemon who I created a pattern for just to see if I could. It took quite a bit of yellow 4ply yarn with some bits of black, white, and red 4ply yarn thrown in. I used 4 Size 2 Double Pointed Needles, a decent amount of stuffing, and a stitch counter to keep track of my steps. I suggest also using a stitch marker to keep track of when you finish a round.

This pattern incorporates a technique known as W&T, (Wrap and Turn), which is probably the most difficult thing to do in this pattern. It is NOT that hard and there are plenty of tutorials for W&T for knitting in the round on YouTube.
