Well, you did ask me to build a snowman…
Sorry, couldn’t help myself, I apologise for the Frozen reference if you’re sick of them. On the plus side, a couple of parts were a bit challenging to achieve with just 3D primitive objects.
Since Unity doesn’t have a built in cone, his nose is built out of several cylinders with decreasing radius. You can see this better on the below picture.
His mouth is actually made of five quads that have been scaled and arranged into something that vaguely resembles a mouth. Oh, and I’ve used two scaled cubes for his front teeth.
All in all, I’m pretty happy with how close I got to the source image:
