What does catepillar furn and mold have in common?

Caterpillar, furn, and mold all relate to the processes of transformation and development. Caterpillars undergo metamorphosis to become butterflies, while molds, in the context of fungi, reproduce and grow through spore formation, often transforming organic matter. "Furn," although less commonly referenced, can imply a furnace or environment where materials undergo change through heat. Together, they symbolize stages of growth and change within biological and physical systems.
