1In large bowl, mix cereal and chopped cookies. In 2-quart nonstick saucepan, melt butter. Add marshmallows; cook and stir over medium-low heat until marshmallows are completely melted. Pour over cereal mixture; mix until coated.
2Line cookie sheet with waxed paper; spray paper with cooking spray. Spray 3 3/4-inch open gingerbread man cookie cutter with cooking spray; place on cookie sheet. Spray hands well with cooking spray. Firmly pack cereal mixture evenly into cookie cutter, filling cutter completely; push out of cutter. Repeat until all mixture is used. Let stand until set.
3In small resealable freezer plastic bag, place baking chips and oil; seal bag. Microwave on High about 1 minute or until softened. Gently squeeze bag until mixture is smooth. Refrigerate 2 minutes or until slightly set. Cut off tiny corner of bag; squeeze bag to pipe melted chips over cookies as desired to decorate, using small dots to attach candy. When decorations are set, cut strips of fruit snack and tie around necks for scarves.
