Answer 1

"The Valley of the Jolly Green Giant" refers to the Minnesota River valley around Le Sueur, Minnesota.

Answer 2

It is "The Valley of the Jolly Green Giant" -  A fictional place where they grow food. It could be anywhere in the green belt.

Answer 3

Keep thinking that advertising slogans and symbols are real.  Energizer Bunny, Flo from  Progressive, Unk Ben, Aunt Gemima, and many others will rule your life.

I still like "Reddy Kilowatt" from the 1950s.
