Wiggle and Waggle and The Big Fat Cow That Goes Kapow

Wiggle and Waggle by Caroline Arnold, illus. by Mary Peterson is an easy reader about two worm friends and the work that they do in their garden. My favorite part is their digging song:
"We wiggle and waggle, squiggle and squirm.
Digging in dirt is the life of a worm.
We dig and we sing all day long,
Our wiggly, waggly, gardening song."
 The story is followed by information on how worms help plants grow and other worm facts. Color illustrations throughout.

 The Big Fat Cow That Goes Kapow is by Andy Griffiths, author of  The Day My Butt Went Psycho, and his early reader books have been described by School Library Journal like so: "Imagine the outcome if Dr. Seuss, Dav Pilkey, and Lane Smith were locked in a room until they came up with a book for beginning or reluctant readers." For me, this title will be an acquired taste, but that will hardly matter to kids who giggle over his tales of  a rock-and-role mole, Ruth and her super-loud hooter horn and yes, an exploding cow or two.
