Pour the water to get the duck into the tub! Tap anywhere to bring the pipe down and begin pouring water. The water will run for as long as you keep your finger held down. When you're finished, release and the pipe will go away. Pour the water at the correct position so the stream carries the duck into the bathtub.

Use your water carefully because you only have a limited supply. The amount of water you can use will be shown in the upper left corner of the screen. Use even less water to earn three stars in the level.

In later levels, there will be a variety of objects you can use to your advantage. Portals are orange swirls that come in pairs. If the duck goes through one portal, it'll fall out of the other portal. Water can travel through the portals too! Blue boxes act as barriers that can be carried by the water and protect the duck from spikes. White stones are heavy, but if you pour water next to them, the stone will roll and can help push the duck into the tub. Platforms with a tiny circle in the middle will rotate if anything - including water - falls on top of it. Conveyor belts will push the duck in the direction of their rotation.

Lastly, don't let the duck touch the red spikes - those aren't very helpful!
