As it says first head over to Breakwater Beach, on the right side of the beach near Cecil's Beach Hut Store there is a Sea Horse, this is the Sea Sprite. Click on him and he will give you a clue to the question. Then head over to Presto's Edge walk strait across and you should see a brown chest, this is the trivia chest. Click the chest and a question come up, answer the question correctly and you get 250 coins. NOTE: If you fail, wait about 10 minutes and try again.
