Where's My Water?
Certain levels are also populated by hazards that must be avoided or removed. For example, some levels contain algae that will absorb water and grow, while bombs destroy all objects and/or kill all the rubber ducks in the bomb's vicinity. Other types of fluids will sometimes appear, such as purple poison/acid, reddish mud, and green ooze/slime. If either poison, ooze or mud reaches the inlet, the level is failed and must be restarted (Swampy jumps out of the tub if poison/acid enters it, but simply gets surprised or disgusted if ooze/slime or mud enters it instead). If all the water or any fluids that must be converted disappear, Swampy simply mopes as the level restarts too (in the free version of this game or any version of the game until 2013, he mournfully cries as a result of failure). The poison, mud, and the ooze will kill all the rubber ducks (they turn into uncollectable skulls and make a painful-sounding quack) on contact, as well as bombs when the ducks are in the vicinity of them.
