In May 2013, a new subset of levels called "Allie's Story" was added in a May 25 update. The gameplay in this mode is the same as the other modes, but this time, it requires players to direct steam to operate Allie's makeshift pipe organ. Ducks are blue and can only be covered in steam, while other fluids (except clean water) will kill them. If water or other fluids get in the inlet, the level is failed. As with Cranky's Story and Mystery Duck, a one-time in-app purchase is required to play beyond the first five levels.
