The great eggscape!

"The Good Egg and his pals escape their carton and drop into the store for a morning of fun, enjoyed by everybody. Well, almost everybody. Shel (an egg) isn't a huge fan of group activities, especially when he's made to be 'It' for a game of hide-and-seek. Nevertheless, Shel doesn't want to let his friends down, so he reluctantly plays, anyway. But after a morning of hiding and seeking, somebody's still missing. Will the dozen eggs friends ever be reunited?"--OCLC.
