Need Golliwog pattern please.

Gollis are very politically incorrect in today's world...

That said, there are a few knitting patterns out there, but I have not seen any crochet ones. 
Any good amigurumi doll would do, done in black thread or yarn.

Your only concern would be hair and facial features. Here is a Pinterest page devoted to golliwogs, you can use the images to help you craft one for any doll pattern.
