This needs to be renamed. The description even says that many examples of this trope are not MacGuffins, the page image does not even feature a single MacGuffin. It is not worth the added alliterative appeal if it is incorrect.

What of the Pearl of Wisdom from the "Ducktales" episode of the same name? A sea-faring thief named Sharkey sells the titular gem for a nice sum to Scrooge Mc Duck, who knows of the magic of the pearl. When both end up on the pearl's Island of Origin, both are struck by sunlight and given flashes of wisdom (which was part of the magic: you had to be touching the pearl at first sunlight to receive it), causing both of them to see sense uncharacteristic of them (Sharkey realizes he needs to go straight, Scrooge realizes the pearl rightfully belongs to the Islanders).
