Blubbery describes something that is soft, fatty, and jiggly, like the thick layer of fat under a whale's skin. Whale blubber keeps these ocean giants warm in freezing water, sometimes measuring over a foot thick. When something feels or looks blubbery, it wobbles and shakes when you touch it, similar to how gelatin jiggles on a plate.

For centuries, sailors hunted whales for their blubber, which they melted down into oil for lamps and other products. Scientists have discovered that blubber is a specialized tissue that helps whales and seals survive in frigid ocean temperatures that would kill most other mammals within minutes.
