The final page of Pussy willow reads:
"'Everything that anyone would ever look for is usually where they left it,' hooted the owl. "On a bush," sang the robin. 'In the sky,' sang the lark. 'In a song In the Spring In the dark.' Then up popped Pussy Willow. 'Everything that anyone would ever look for is usually where they find it,' purred Pussy Willow."
Brown, Margaret Wise. Pussy Willow. New York: Golden Press, 1979.
Pussy Willow goes on being himself (before realizing it) through the process illustrated in the book of finding himself. Each animal he asks for help along the way can only answer Pussy Willow's question through his or her own lens.
