I'm a Frog! (An Elephant and Piggie Book)
Gerald and Piggie are best friends.
Gerald is careful. Piggie is not.
Piggie cannot help smiling. Gerald can.
Gerald worries so that Piggie does not have to.
In I'm a Frog! Piggie has some ribbiting news! Can Gerald make the leap required to accept Piggie's new identity?
