This is a pattern for the Pokemon Onix. Medium sized, roughly 9 inches long at the end, but size will vary by tension or the size of hook you choose to use. Would say it is easy/ medium difficulty and requires a good understanding of crochet to be able to successfully read the pattern.

Outside of standard crochet materials, you will also want a means of making details like the eyes on this pattern. I used needle felting, but you could also just cut some felt and glue it.
