I Don't Want to Be a Frog - Dev Petty

Absolutely fantastic story. Not only does it explain the reasons this little frog can't be a cat, rabbit, pig, or owl, but it also has a super funny ending that makes him happy to be exactly what he is - a wet, slimy, bug-eating frog. Super cute.  Also, the last page sets it up perfectly for kids to write their own "I don't want to be a ...." story.
