Marshmallow

The Marshmallow (not to be confused with Marshmallow Guy) was a Marshmallow in Super Nintendo Bros. Brawl. He escaped a kid who tried to eat him and escaped to his homeland, Marshlandia. However his friends then ate him. The death of Marshmallow was actually filmed and parents were concerned about their kids watching Marshmallows being eaten. However then, Nintendo reminded the parents that the kids do the same.
