I start as sap from forest veins, then heat transforms my polymer chains. I stretch, return, and still endure, made strong and flexible through fires cure.

A time when I'm green, A time when I'm brown. But both of these times, Cause you to frown. But just in between, For a very short while. I'm perfect and yellow, And cause you to smile. What am I?

I don’t eat breakfast, I don’t have feet, But I love a tree stump to feast

I drift across the silent ground, a gentle glow without a sound. Born of distant fire, yet still I gleam, a borrowed light, a midnight dream.

I swallow the unwary, but have no mouth. I hold you fast, but have no hands. The more you struggle, the deeper you sink. What am I?
