I am not a crocheter, yet even I managed to puzzle out how to do this. The pattern is simple and straightforward, with links to any information you may need, e.g. mirror crochet.

I’m very happy with how he turned out, the only change I made to the pattern is sewing the top of the mouth to the bottom along the back of the head so a line of beige wouldn’t peek through. I suspect that was needed because I may not have assembled him correctly in the first place.
