20% smaller than the regular Mr Sleepynose. A charming and cute solution to common house odors! simply open Mr Sleepynose's head, put in 1 and a half or 2 teaspoons of baking soda (you can find this in any supermarket), close his head, and place him in a fridge, near laundry, a pet pen, or any place in the house with odor. His nose will soon reduce the burden of odor on our noses! He can either lie flat or be hung from the hook above his head. All you would need to do is replace the baking soda every few days to kill odors!
