Polar Bear's Underwear by Tupera Tupera*

Polar Bear is horrified to discover that he forgot to put on his underwear for the day.  As he searches for them, the reader is able to view various other animals' underwear!  The reader can predict which animal will be on the next page by the type or design of the underwear.  Underwear cutaways permit the reader to view the underwear but not the animal wearing them.  The following page reveals the animal.
Funny ending!
