A simple book--two books in one that end in the middle--with a salubrious message: ""Sometimes, you just feel happy"" and ""Sometimes, you just feel sad."" In the first half of this book a troop of animals savors its happiness--a peacock parades while a tiger is tickled. In the other half, which must be flipped over to be read, a collection of beasts fares less well--a bear broods and a camel curls its lip. This companion to Wide Awake/So Sleepy (1994, not reviewed), with some inventive anthropomorpization, lets children know that it's okay to go with the flow. Paschkis's colorful portraits display a whimsical use of perspective and amiable animals who are expressive without being cute; the background patterns bloom in a robust palette.
