How Do Animals Do That?

Inside a cocoon, a caterpillar undergoes metamorphosis, emerging as a magnificent butterfly. Cats' tongues are covered with countless tiny, hook‑shaped papillae that feel rough, enabling them to groom efficiently and to scrape meat cleanly from bone and to remove debris.

Secret Transformation is a programme presented as a single episode, focusing on two seemingly unrelated natural wonders. The title hints at the changes explored within the show, and the format follows a concise, episode‑length structure that keeps the content tightly packaged for viewers. The first segment follows the remarkable journey of a caterpillar as it undergoes metamorphosis inside its cocoon, emerging as a butterfly. The episode walks the audience through each stage of this transformation, highlighting how the creature reorganises its body while concealed within the protective casing, ultimately emerging with wings. The latter part of the episode shifts its attention to felines, offering a collection of facts about cats’ tongues. Viewers are introduced to various aspects of feline oral anatomy, learning why a cat’s tongue is distinct from those of other animals. By pairing the story of butterfly development with insights into cat tongues, Secret Transformation provides a brief yet varied look at nature’s adaptations, delivering educational snippets that are both engaging and easy to digest.
