Think about home, lightness. Lightness helped float in home, but no more. Must live at bottom of lightness now. A small brown crawls by. Up more rocks.
Back legs are stronger still, so jump.
Jump carries out over home. But front legs can pull on lightness. Floating in lightness is not like floating in water. They will gain strength. Home lies below, and the bright part of lightness scatters across top of home.
