This pattern is part of the Mix and Match Menagerie series of patterns by Abbys Crochet Plushies that are made with separate heads and bodies joined together by a stick. The heads and bodies of different patterns can be mixed and matched with others in the series. They are made using 4 Seasons 8 ply Marvel 100% acrylic yarn with a 2.5 mm hook, but any yarn and hook can be used as long as your consistent. Here is a link to a tool to find different combinations to mix and match.
