Description: An unhealthy fern sulks at the bottom of the forest floor. She aspires to grow tall like the tallest tree in the forest, but she realizes something’s wrong: she’s not growing at all; she can’t repair her leaves; and she feels awful. Fern calls Mosa Mack for help. Mosa consults with a wise canopy layer and a singing chloroplast to help her solve Fern’s mystery.
