Dr. Freezegood

Dr. Freezegood is a snowman wearing a fezz hat in Super Mario World 2: Yoshi's Island. They ride ski lifts in world 5 and stand completly still unless they drop off on a slope. You cannot eat them, but you can step on their heads to rack up a few Coins. They're harmless to touch, the only problem is they hog up the ski lift platforms.
