In January 2012, "Cranky's Story", a new subset of levels within the game, was added initially to the iOS version and later to the Android version. The gameplay in "Cranky's Story" is basically the same as the main game, in that players must route a fluid to an inlet goal. However, this time the player must help Cranky by bringing the purple poisonous water into his lair to melt algae that is covering his food. This time, the ducks are now purple and can only be collected by being splashed with poison, while other fluids (including clean water) will kill it. If water or any of the other liquids enter the inlet, the level is failed (the water causes Cranky's food to be covered with more algae, surprising him, while ooze will turn it into a rock and being kicked away, the same is true with mud). If all of the poison is lost, then Cranky will get very angry. The first five levels in the first chapter, "Cranky's First Course", are free to play, while the rest of the chapter and all of the 2nd chapter, "Hunger Pains", are accessible through a one-time in-app purchase. The update also includes "Cranky's Challenge", a set of 12 challenges and four bonus stages for the player to accomplish. If those challenges are failed, then Swampy will cry as if you lost all the water. An all new Food Groups and the 3rd episode "Bulking Up" were released on April 5, 2012 and adds 6 challenges and two bonus stages. The final episode, "Overstuffed", was released on May 18, 2012.
