Building a playhouse along with her beloved father, Nelly Gnu accompanies him to the store and is accidentally separated from him while searching for the perfect paint.

"When a box of cell phones is accidentally delivered to the zoo, one blue gnu quickly calls two white sheep, who plan a party - beep beep beep! Call by call, the party spreads around the zoo, but oh no! Who invited tiger, and who will he call on his new phone? A fun and colorful picture book romp, where we count from one to ten and down again in one huge party!"-- Provided by publisher.
