1. Place 2 scoops of strawberry ice cream in a chilled bowl. Chill in the freezer while preparing decorations.
2. To make snout, cut a marshmallow in half crosswise, and stick 2 brown mini M&M's into the sticky side of one half of the marshmallow. Dip the same side into pink sanding sugar to coat sticky surface. Cut the remaining marshmallow half into quarters to make ears, dipping the sticky side of each quarter in sanding sugar. (Discard or snack on the remaining two quarters.) For the legs, cut 2 strawberry wafer cookies crosswise in half. For heart, cut a deep V in the strawberry slice.
3. Remove bowl with ice cream from the freezer. Place snout in center of top ice cream scoop. Place ears on top ice cream scoop. Attach 2 candy eyeballs for eyes. Push legs into the second ice cream scoop. Place the strawberry heart in center of bottom ice cream scoop. Carefully spoon chocolate sauce around the piggy.
