This is an easy pattern to follow only using single crochet, increase and the invisible decrease. It’s worked from the bottom up. If you want to make it smaller you could use a smaller hook and lighter weight yarn.
You can use Red Heart Super Saver or I Love This Yarn in White for the tooth, a little bit of Black yarn for the smile and Yellow for the Crown.

Hook Size: 3.75mm/F hook

Yarn: I Love This Yarn in White, small amount of Black for mouth and Yellow for the Crown (or any worsted weight yarn will work)

Supplies: Two 12mm Safety Eyes, Tapestry needle, stitch marker
