The Sick Giraffe Named Frank

Once there was a giraffe named Frank.
Frank never went outside because he thought he would get some kind of sickness,
worse than the one he already had!
Frank thought he had some sort of sickness because he had brown spots all over him!
He thought it was brown chicken pox (even though he didn't know what that was).
So Frank's life wasn't fun, or silly, it was just boring.
