Fluffy Puff Marshmallows is the fictional marshmallow brand from the Homestar Runner web cartoons, fronted by Marshie, an enthusiastic marshmallow mascot who stars in its parody commercials. The jingle mimics the bright, catchy style of classic television snack ads, which is why it became a favourite reference for fans of the series. As Homestar Runner clips circulated online, the tune survived as a short, instantly recognisable piece of early internet humour, still reused today for nostalgic edits and light-hearted meme videos.
