Several days in advance, make fondant pieces: Knead 2 teaspoons Gum-Tex into 1 pk. rolled fondant. Tint a 1 1/2 in. ball of fondant green, for band of hat, wrap in airtight plastic and set aside. Divide remaining fondant in half and tint black and tan (for tan, combine light golden yellow with a small amount of brown). Make hands: roll out tan fondant 1/4 in. thick. Cut two hands, reverse one. Trim a small amount off the wrist, and insert end of stick to create a hole on which the hand will later be attached to the cake. Remove stick, place hands on cornstarch dusted cake board. Let dry several days. Make birds: cut two birds, reverse one. Trim both slightly smaller. Place on cornstarch-dusted board. Using a sharp knife, cut slits for tail feathers. Allow to dry thoroughly. Using tip 3 and buttercream, pipe dot eyes and fill in beak.
