The search for extrasolar planets has yielded a bounty of results, with over 5,000 confirmed planets catalogued so far. Among those planets are a strange and as-yet-not-well-understood type of low density gas giant often referred to as 'cotton candy' planets or 'Super-Puffs'. While that's not a breakfast cereal coming to a grocery store near you, they are an intriguing type of world. And recently, a new paper announced the discovery of TOI-3757 b -- a hot Jupiter with the density of a marshmallow.
