a friend of mine had asked me to make him one of these a while ago when I was first learning how to crochet, I'm glad that I was finally able to give him his Boo! Looking up the refs brought back alot of memories of gaming past.....
He's made with acrylic, polyfil, safety eyes, and felt embellishment (cutting out his teeth was by far the hardest part^^) and he's about the size of a baseball.
You can buy your own Boo in my Etsy Shop: http://www.etsy.com/listing/75094233/crocheted-boo-from-super-mario?ref=pr_shop
