Heat oven to 400. Line 2 1/2 inch muffin cups with baking wrappers. In large bowl, whisk together cake mix, the water, orange juice, eggs and oil until smooth. Spoon batter into prepared cups until they're about 3/4 full.
Trim a half inch from the pointed end of each pear slice. Pretending the muffin is a clock, insert the flat trimmed end of one at 11:00 and another at 1:00, leaving the tops of the slices exposed for ears.
Bake for 20 minutes, or until muffin tops spring back when you touch them. Let cool 5 minutes in pan; remove muffins and place them on wire racks. While they are slightely warm, add almond slivers and choc. chips to create the bear's face.
