Mr. Green, a cookie-loving alligator, followed his nose to a freshly baked tray of cookies and discovered an odd note warning they were terrible.  This was strange because Mrs. Green always baked wonderful cookies!  After investigating the ingredients, he decided to taste one.  Delicious!  Then he wondered about the others.  Just as he finished the last one, Mrs. Green returned home.  She showed him how he had misread the note and told him she had doubled the recipe – and the rest were ready to bake.  Mr. Green began calculating how many cookies there would be if one kept doubling the recipe!  Bright, colorful acrylic artwork beautifully illustrates the text.  Originally published in 2006 as On the Go with Mr. and Mrs. Green, the new 2012 edition changed the title to Cookies.
