"The Case of the Missing Pearl" is a Polly Pocket webisode.
"Lila lost her pearl! Which one of these oysters took it from her? Find out what happens in this video with Polly and friends at the beach."
Polly, Lea and Lila go to the beach. When they're about to go boogie boarding, Lila notices that the pearl from her necklace is missing. She accuses an oyster of stealing it and wrestles it until she takes its pearl. Suddenly, a bed of oysters surrounds Lila and they spit their pearls at Lila. Lea notices that Lila's necklace was the wrong way around, so the pearl was hanging behind her instead of in front of her. Lila apologised to all of the oysters and gave them back their pearls.
