Where's My Water?
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 filled 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 and impatient over the loss of the poison.
