In March 2011, a new "interactive queue" debuted at the Walt Disney World location, with new crypts and tombstones honoring Imagineers; a murder mystery for guests to solve featuring the sinister Dread Family; the Composer Crypt, which features musical instruments that play variations of "Grim Grinning Ghosts" when touched; the Mariner's brine-filled sepulcher, whose ghost sings and sneezes from within, and a crypt for Prudence Pock the poetess, which features haunted moving books & Prudence's ghost writing invisibly in her poem book. Guests can solve the unfinished poems by speaking into microphones located on the crypt. The FastPass+ line skips the queue altogether and leads guests straight to the Foyer doors.
