Chacha and the pearl necklace

Chacha is an Emperor penguin, the largest of all the penguins that lives in the Antarctic. Chacha loves to play and swim with friends. One day while Chacha was playing dress-up with Gigi, her friend, and Chacha tried on her mother's favorite pearl necklace. When Chacha is ready to put the necklace away, she notices that a pearl is missing. Chacha knows she isn't allowed to play with the necklace so Chacha and Gigi look high and low for the missing pearl. Can Chacha find the pearl before her mother misses it or should Chacha just tell the truth and ask for help?
