A bear is a bear (except when he's not)

"When Bear wakes up early from his hibernation, he can't remember what he is! Is he a bird? Or a moose? Maybe a fox? Just when it seems like Bear won't be able to figure it out, he finds his cave and decides another nap might help. Will Bear be able to remember what he is when he wakes up again in the spring?"--OCLC.
