Freddi Fish 3: The Case of the Stolen Conch Shell[]
Prior to the game's start the Great Conch Shell was stolen by a surprise thief. Since Uncle Blenny is the grand, exalted keeper of the Conch, he was considered the prime suspect and was subsequently sent to jail. The Golden Pipes fell out of the conch when it was taken and were left in three different locations through unknown means (or by Nadine in her ending).
Later, when Freddi Fish and Luther arrive at the festival, Uncle Blenny requests their help in proving his innocence by finding the missing Conch Shell and the Golden Pipes.
Once all the pipes are found, Freddi Fish, Luther and Old Soggy track a thief at the ancient underwater pyramid. The thief somehow escapes but accidentally drops the bag with the evidence inside. When Freddi and Luther tells the crowd that Uncle Blenny is innocent, they pull one of six clues out of the bag and points out who the real thief is. Once the thief confesses his/her actions, he/she returns the conch shell to Uncle Blenny which he repairs and subsequently blows into to start the Founder's Day Festival, making the game end with an announcer, who says something about the thief and signs off by saying "Case closed!".
