So things all started to go wrong when Popeye's father, who looks exactly like him except more wrinkly, got jealous of his son's supply of spinach and his girlfriend and decided to force Popeye to leave the country. Now, in "Farm Implements and Rutabagas in a Landscape," Popeye sits somewhere in the countryside and hurls green thunder that blocks the sun and creates perfect darkness. But, don't worry, it's not mad thunder; it's "loving thunder," and Popeye is very happy in the end. It's a transformation all right...we're just not sure how else in the world to describe it.
Popeye's exile from the country is the cause of transformation in the poem.
