Yucky Worms by Vivian French illustrated by Jessica Ahlberg*

A boy and his grandmother are enjoying the day together in the garden.  When the grandmother digs up a worm, the boy reacts with a huge "yuck"!  The grandmother proceeds to share all the worm's positive attributes.  Smaller text is inserted within the illustrations, containing more facts.
I love the layout and illustrations.  The worms offer humorous comments throughout the book.
Text features: different size font, index, cross sections, diagrams, close up
*Highly recommend.
