Update: Disney’s fourth S.E.A. riddle appears to point to the Ridge Jewel as the missing artifact. A fifth riddle adds more clues, but the thief’s identity and the timing of the fictional theft remain unanswered.
Disney began the online clue hunt to introduce a new Society of Explorers and Adventurers character. The riddles draw on Disneyland, but anyone can solve them from home by looking up park images online.
The story began at D23 in August, when Imagineers opened a S.E.A. archive crate and found bricks and a note instead of the artifact inside. In the mystery, a thief leaves riddles that each lead to a letter. Players must put the letters in the right order to reveal the character.
The first three riddles produced T, L and A. The letters are scrambled, and Disney has not revealed the new character. Disney is adding new riddles to its clue-hunt page.
